I need an explanation for this Statistics question to help me study.

This is the second of two sections for your Data Analysis Assignment. In this section, you will complete a one-sample t-test on new data and interpret the results. This Data Analysis Assignment focuses on the application of the One-Sample t-Test. While completing this assignment contemplate: What are some ways in which the one-sample t-test can be useful? Will this analysis play a role in your own research paper plan?
Review & Reflect
In this Data Analysis project, we will be examining the distribution of three common areas of academic study and comparing these to the known mean in the overall population. Fifty students in this class have taken three measures of academic success — Math, Reading, and Spelling. As the teacher you know that each test has been used nationally and know that the expected means for each test are:

• Math –μ=55

• Reading μ=62

• Spelling μ=83

You want to know if your class is significantly different from the expected mean from the population. The data for your class of 50 students
1. State your null and alternative hypotheses.

2. Is this a one or two-tailed hypotheses? Explain.

3. Calculate the appropriate statistical test. (If you get stuck, refer back to the video from 2a or see the description in your book)

• Be sure to include measures of central tendency and variability in your analysis/writeup.

4. Can you reject the null hypothesis? Why or why not?

5. Write a results section for your findings.

• Include the descriptive statistics, type of statistical test, and results of the tests, with effect sizes and confidence intervals.PJM380 MOD2 Discussion Post 250 words APA cited reference

Assume you are drafting an email to a colleague to explain how he/she can use Excel to solve one of the economic models used for project selection. Provide a detailed, step-wise instruction for one of the economic models discussed in Chapter 2 of the textbook and specify the inputs, Excel formula, and output data. You can use Lynda.com to review videos that provide additional information on economic models.

Be sure to post an initial, 250-word substantive response by Thursday at 11:59 p.m. MST and respond to two or more peers with substantive responses by Sunday at 11:59 p.m. MST. A substantive initial post answers the question presented completely. Substantive peer responses ask a thoughtful question pertaining to the topic and/or answer a question (in detail) posted by another student or the instructor. Or, you can include applicable personal experience or additional resources concerning the discussion topic.

Reference at least one credible source among the required or recommended readings and an outside, credible reference (a reference other than the textbook or readings), cited according to proper CSU-Global Guide to Writing and APA (Links to an external site.) standards.

Hey Colleagues,

Another interesting challenge for us in the Discussion in Module 2. We are now delving into the economic models used for project selection. Pick one of the models discussed in Chapter 2 of the textbook. Talk to the inputs for the model you choose, describe (provide a graphic if you will) the MS Excel formulas, and then the output. There are videos on Lynda.com that will help.

If you have personal experience with the selection process and have used a model to assist – tell us about it.Final assignment for class: assignment help online
I’m studying and need help with a Law question to help me learn.

To conclude this course, you will examine the impact of police misconduct and technology on the operation of police agencies. Administrators and political officials must consider these strategic questions. Based on your readings, research, and discussions with peers, prepare a report in 8–10 double-spaced pages using Microsoft Word that explores these critical issues in contemporary law enforcement. Your report should address the following questions:
Evaluate the current status of the Los Angeles Police Department. Have the issues from the Rodney King era been resolved? Explain how changes in recruitment and training can address the problem of police brutality and excessive use of force. Use research to provide examples from actual departments. Discuss the use of GIS and other advanced technology in today’s police environment. Consider recent developments such as drones and automated license plate readers. Do these technologies present civil liberty problems? Examine any of the consent decrees accepted by a municipal police force and summarize the reasons for the decree and its provisions. Analyze how well the city in question has complied with its requirements.
*THIS IS THE FINAL ASSIGNMENT!!! PLEASE KEEP THAT IN MIND*
