I’m studying for my History class and don’t understand how to answer this. Can you help me study?
This essay has to frame the 15-M protests within its own pertinent historical and economic period. In order to do so, you may want to structure the content of your paper in a way that you are able to answer all the questions related with this movement.
A) What was the 15-M and when and why did it take place? Many articles to go along with those two questions. At the same time, take into consideration the nature of the economic crisis of 2008.
B) What were the main claims? Was the 15-M a response against the Spanish government or did the 15-M have a wider target?
C) A very important topic related with the 15-M is the way in which they occupied public spaces, such as Plaça Catalunya or Plaza del Sol in Madrid. For this reason, it is important that you explain how did the Spanish citizens organize their assemblies as well as the role of media.
D) Was the 15-M just a Spanish movement? In other words, can you relate this movement with anything that took place in the US? This part should present a strong intercultural reflection.

#You are told that in Providence Rhode Island the height of women averages 64 inches (5’4″) with a standard deviation of 1.5 inches.
#Of the 178 thousand people in Providence Rhode Island, 52% are women.
#PART 1
#1.1) Simulate the population described above. Call the population variable popri
#1.2) Compute the mean and sd of this population.
#How does this mean and sd compare to the true mean (64) and sd (1.5)?
#1.3) Plot a density plot of this population. What does this distribution look like?
#PART 2
#2.1) Take a random sample of popri containing 10 people and call the variable sam10
#2.2) Compute the mean and sd of the sample sam10
#2.3) Take a random sample of popri containing 1000 people and call the variable sam1000.
#2.4) Compute the mean and sd of the sample sam1000
#2.5) Which is closer to the true population mean and sd; the sample with 10 people or the sample with 1000 people? Why?

#Ex: What is the probability of a student getting a 75 or less on the exam
#2) Quantiles from a Normal Distribution using qnorm(Z, mean, sd)

#1. Simulating Populations using Random Variables
#——————————————————–
#The difference between a population and a sample:
#Your sample is the group of individuals who participate
#in your study, and your population is the broader group
#of people to whom your results will apply.
#Therefore: “population” in statistics includes all members of a defined group.
#A part of the population is called a sample.
#^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
#Last week (Lab 3), we used the command rnorm()
#to create a variable with a normal distribution
#Random Normal variable: rnorm(n, mean, sd)
#NOTE: We can specify how large our population is,the mean and SD.
#^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#
#EXERCISE 1-1:
# Create a normally distributed population variable called pop
# that consists of 10,000 subjects with mean of 15 and sd of 2
#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#
#set.seed(1)
pop = rnorm(n=10000, mean=15, sd=2)
#Let’s verify that this did what we wanted.
hist(pop); mean(pop); sd(pop)
#??????????????????????????????????????????????????????????????????????????????????#
#Thought Question 1: Why is your mean and sd for pop slightly different
#than mine OR rather, why is noones exactly a mean of 15 and sd of 2
#??????????????????????????????????????????????????????????????????????????????????#
#??????????????????????????????????????????????????????????????????????????????????#
# Now, let’s pretend this variable x is a population of
# undergrads + graduate students at USC who have ever used marijuana
#Thought Question 2: Considering that USC is ~20k students,
#In reality, could I actually collect this information from every USC
#student to form this distribution? What should I do instead?
#??????????????????????????????????????????????????????????????????????????????????#
#—————————————————————
#2. Taking Samples from a Population: The sampling Distribution
#—————————————————————
#All (most) research studies deal with samples
#We can take a sample from data we consider to be our population
#by using the sample() function in R
#^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^#
#Random sample:sample(x, size, replace=TRUE)
#^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^#
#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#
#Example 1: Let’s pretend we are researchers.
#While ideally we would like to study the POPULATION of marijuana users
#at USC, we realize that we only have funding to ask 200 students.
#We can see what our data might look like if we take a sample from
#the population variable pop.
#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#
sam = sample(x=pop, size=200, replace=TRUE)
#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#
#Exercise 2-1: Calcualte the mean and SD of the sample sam.
#How do these results differ from the means
# and SDs in the pop variable?
#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#
mean(sam); sd(sam); hist(sam)
#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#
#Exercise 2-2:
# A) Create a random sample called sam20 from pop containing 20 subjects.
# B) Create a random sample called sam750 from pop containing 750 subjects.
# C) Compute the Means and SDs for sam20 and sam750. Create Histograms for both.
# D) How do the means from each sample compare to the true population mean of 15?
# E) Is there an association of the number of people in the sample with the magnitude of
# the difference from the populaton mean?
#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#
#A)
sam20=sample(pop, 20, replace=TRUE)
#B)
sam750=sample(pop, 750, replace=TRUE)
#C)
mean(sam20); mean(sam750)
sd(sam20); sd(sam750)
plot(density(sam20)); lines(density(sam750), col=”red”)
#D)
abs(15-mean(sam20)); abs(15-mean(sam750))
#E)
#As the number of people in the sample goes up,
#the mean becomes closer to the true population mean
#—————————————————————
#3. Programming in R: Using Loops
#—————————————————————
#In practice, as researchers we almost always have samples
#and NEVER really know the true population
#Simulating a population and taking samples from it can tell us something
#about how well a given estimator (mean, trimmed mean, median etc.)
#represents a distributions (eg. normal vs skewed)
#To begin to understand how taking samples can give us information about an estimator,
#we need to take MANY samples from our simulated population.
#Let’s say we wanted to have 100 different samples of pop with 200 subjects in each sample.
#We could do this two ways:
#1) Write the function sample() many times
sam1=sample(pop, 200, replace=TRUE)
sam2=sample(pop, 200, replace=TRUE)
# …
sam100=sample(pop, 200, replace=TRUE)
#2) Or use a loop
#^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^#
#Loop over ii: for (ii in X:Y) { # ii is the counter
#COMMANDS WITH ii # X is the first value the counter
#} # Y is the last value of the counter
#^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^#
# x=23+24;x
#print(x)
#Here is a simple loop going from a value of 1 to 10
for (jj in 1:10) {
print(jj)
} #NOTE: When executing the loop,
#you MUST highlight and run the entire loop from { to } including the brackets.
# ii will take the values specified with the “in 1:10” argument
#At first ii = 1, but then will increase by 1 (1,2,3,4,5…) until it reaches 10
#Also we can change ii to be whatever we want.
#Below I’ve used my name to demonstrate this
for (kk in 1:15) {
print(kk)
}
#Back to our goal:
#We want to be able to take 100 different samples of pop with 200 people in each sample
#A good way to do this is to first create an EMPTY matrix to put our data
#into using the matrix() command
mysams = matrix(, ncol=100, nrow=200) #? Why ncol=100 and nrow=200?
#Then we can use a loop to place each of our samples into a column of this empty matrix called “mysams”
for (ii in 1:100) {
mysams[ ,ii] = sample(pop, size=200, replace=TRUE)
}
#Look to your right and double click over ‘mysams’
#—————————————————————
#4. Programming in R: The apply function
#—————————————————————
# We just learned how to use a loop to take MANY random samples
# from a population variable. While the purpose of this
# may not be clear just yet, it will be later on in the semester.
#Once we have our dataset containing 100 samples of 200 people, I’d like to find out the mean of each sample
#I could do this two ways:
#1) By manually doing it
mean(mysams[,1])
mean(mysams[,2])
#…
mean(mysams[,100])
#2) By using a loop
for (jj in 1:100) {
print( mean(mysams[,jj]) ) #I have to use print() here because things in loops don’t get output to the screen without it
}
#However, I don’t just want to KNOW the means of each sample, instead I’d like to have a variable
#where each observation is the mean of a given sample so that I can analyse the means of the samples
#We can do this by first creating an empty Vector of length 100
sam100means = numeric(100)
#And then using a loop to populate the vector
for (jj in 1:100) {
sam100means[jj] = mean(mysams[,jj])
}
#With this, I can examine the average (mean) of the means for each sample
mean(sam100means)
#And their distribution
hist(sam100means)
#There is an easier way to get this sam100means variable,
#We can use the apply() function!
#^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^#
#Collapse Data (apply): apply(X, MARGIN, FUN)
# X=dataset; MARGIN: 1=Rows, 2=Columns; FUN=Function
#^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^#
#I will create a variable called sam100means2 containing the column means of mysams
sam100means2 = apply(X=mysams, MARGIN=2, FUN=mean)
#In the above: MARGIN=2 tells R to do the operation on the columns
#FUN=mean tells R to take the mean
#A Density plot of this:
plot(density(sam100means2))
#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#
#Exercise 4:
# A) Create a variable called sam100sd that contains the standard deviations of each
# sample from mysams. Use whatever method you prefer to do this.
# B) Show a density plot of the SDs from mysams
#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#
#A)
sam100sd = apply(X=mysams, MARGIN=2, FUN=sd)
#Alternately
sam100sd1=numeric(100)
for (i in 1:100) {
sam100sd1[i]=sd(mysams[, i])
}
#B)
plot(density(sam100sd))
#—————————————————————
#5. Sampling Distribution of the Uniform Distribution
#—————————————————————
#While we’ve seen that the distribution of means
#from random samples taken from a NORMAL population
#are normally distributed, what if our population is not normally distributed?
#Let’s see for example the uniform distribution
# which can be created using the runif() function
#^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^#
#Random Uniform variable: rnunif(n)
#^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^#
#I’ll create a uniform population distribution of 10,000 subjects
popunif = runif(10000) #Unifor distribution
#This distribution looks like:
hist(popunif)
#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#
#Exercise 5:
# A) Create a matrix called unifsams that contains 150 random samples of 250 subjects from popunif
# B) Create a variable called unif150means that contains the means for each of the 150 samples
# C) Create a density plot of means in unif150means. What does this plot look like?
#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#*#
#A)
unifsams = matrix(, ncol=150, nrow=250)
for (ii in 1:150) {
unifsams[,ii] = sample(popunif, 250, replace=TRUE)
}
#B)
unif150means = apply(unifsams, 2, mean)
#C)
plot(density(unif150means ))
#Normally Distributed remember the Central Limit Theorem.

I’m trying to learn for my Business class and I’m stuck. Can you help?
Few would argue that, in order for a business to sustain its success, there has to be value beyond the mere product or service they bring to the market place. Every business has intrinsic value embedded within their assets. Some of these might be overt while others might be hidden and less obvious. For example, the holder of a patent or a retail store’s location would be considered a key resource.
Research and discuss at least two other key resources that support a business’ success. How does this connect to their customers and ongoing success? Use examples to support your thoughts and ideas!Performance Management – Brochure
I need an explanation for this Management question to help me study.
Evaluation: Assignment 3: Performance Management
Scenario: To prepare for the employee who will be occupying the role, create an employee benefits brochure that you would present to new employees during their initial orientation. Include in this brochure mandatory and discretionary benefits that are used in your industry.
The brochure should be 6–8 pages (sides /panels) with a professional appearance and should be modeled after a professional booklet from your company, a former company, or a company you would like to work for.
Hint: Research various Microsoft brochure templates to create a professional booklet.
NOTE: One of the positions the benefits brochure should be the most applicative to is the job in your description from Week 3. Find creative ways to incorporate your work from that assignment into this one.
Dr. Vic’s Tips: A few things to note here, please use a Microsoft brochure template – you need to do this. Explore MS templates from the main MS Word screen and do a search for ‘brochures’, most of the templates shown will be 6 page/panel (this will be one double sided fold-out page with three panels of information per side) – just like any brochure you might pick up somewhere, it will be one standard sheet of paper, but folded into three panels per side. Also, you need to do this assignment with a company you are familiar with in mind and you need to incorporate information from Ch. 14, and base the job you will offer benefits for – with this brochure, on the job your described in Assignment #1.
Also, below is suggested outline for the brochure, you do not need to follow this outline but you certainly can if you wish.
Side / Panel 1: Cover page: use a graphic for the company and also add the words, “Benefits Brochure”;
Side / Panel 2: Brief description of the company, and description of the job opportunity and how benefits is an extension of overall compensation, (Hint: p.p. 409-411);
Side / Panel 3: Statement on how the company complies with all federal and state mandated benefits including (HINT: Table 4.1, p. 411 – give examples of some of these benefits);
Side / Panel 4: Optional Benefits – list and also describe the type, how much and for how long these benefits can be used. For example, Retirement Plan as a 401K Plan with employer match as 3% of paid salary – or something like that. List and describe at least three optional benefits, as per our textbook discussion on p.p. 417-427;
Side / Panel 5: Family Friendly benefits, please list and describe at least two family friendly benefits as discussed on p.p. 427-428; and list any other benefits offered;
Side / Panel 6: (back page): Contact information for employees with questions.
PLEASE NOTE: after you have finished your brochure using and MS Word template, please save your brochure – you will need to upload it as a n MS word or .pdf document.
