Help me study for my Statistics class. I’m stuck and don’t understand.
please use the number 6 for this question please:
A patient is classified as having gestational diabetes if their average glucose level is above 140 milligrams per deciliter (mg/dl) one hour after a sugary drink is ingested. Rebecca’s doctor is concerned that she may suffer from gestational diabetes. There is variation both in the actual glucose level and in the blood test that measures the level. Rebecca’s measured glucose level one hour after ingesting the sugary drink varies according to the Normal distribution with μ= 140+# mg/dl and σ = #+1 mg/dl, where # is the last digit of your GCU student ID number. Using the Central Limit Theorem, determine the probability of Rebecca being diagnosed with gestational diabetes if her glucose level is measured:
Once? #+2 times, where # is the last digit of your student ID? #+4 times, where # is the last digit of your student ID?
Comment on the relationship between the probabilities observed in (a), (b), and (c). Explain, using concepts from lecture why this occurs and what it means in context.
2. Suppose next that we have even less knowledge of our patient, and we are only given the accuracy of the blood test and prevalence of the disease in our population. We are told that the blood test is 9# percent reliable, this means that the test will yield an accurate positive result in 9#% of the cases where the disease is actually present. Gestational diabetes affects #+1 percent of the population in our patient’s age group, and that our test has a false positive rate of #+4 percent. Use your knowledge of Bayes’ Theorem and Conditional Probabilities to compute the following quantities based on the information given only in part 2:
If 100,000 people take the blood test, how many people would you expect to test positive and actually have gestational diabetes? What is the probability of having the disease given that you test positive? If 100,000 people take the blood test, how many people would you expect to test negative despite actually having gestational diabetes? What is the probability of having the disease given that you tested negative?
Comment on what you observe in the above computations. How does the prevalence of the disease affect whether the test can be trusted?
3. As we have seen in class, hypothesis testing and confidence intervals are the most common inferential tools used in statistics. Imagine that you have been tasked with designing an experiment to determine reliably if a patient should be diagnosed with diabetes based on their blood test results. Create a short outline of your experiment, including all of the following:
A detailed discussion of your experimental design. How is randomization used in your sampling or assignment strategy? The type of inferential test utilized in your experiment. A formal statement of the null and alternative hypothesis for your test. A confidence interval for estimating the parameter in your test. An interpretation of your p-value and confidence interval, including what they mean in context of your experimental designbus315assignmnet10
I’m studying and need help with a Business question to help me learn.
The Department of Defense plans to issue a $400,000 government contract to a company that specializes in drone navigation technologies. As a result, a government auditor has been contacted to examine the operational data VectorCal and one (1) competitor (previously identified as “your company”) in order to decide which company should win the government contract.
Note: You may create and / or make all necessary assumptions needed for the completion of this assignment.
Write a six to eight (6-8) page paper in which you:
Create a one (1) page overview of the history and background of each company vying for the government contract.
Specify at least one (1) of the recent major contracts that was awarded to both companies. Explain the fundamental reasons why both companies were awarded the contract(s) that you specified.
Determine the type(s) of contract for which both companies might be eligible (e.g., fixed-price, cost reimbursement, etc.). Justify the response. Discuss at least three (3) direct costs and three (3) indirect costs that each company incurred during the production of its navigation system. Explain the manner in which this data would factor into your decision as to which company would be more eligible to receive the contract. Suggest which company should be awarded this government contract based on the data that was presented for each company. Next, provide three to five (3-5) reasons to support your stance. Use at least three (3) quality resources in this assignment. Note: Wikipedia and similar Websites do not qualify as quality resources.Constructing the Identity of the ’Youth’: nursing assignment help
I need help with a Sociology question. All explanations and answers will be used to help me learn.
In this assignment you will consider how the categories of “youth” and “childhood” vary over time and across cultures. To do this, you will answer a series of questions regarding photos you select of the “jobs” of young people in three different contexts: (1) 19th and early 20th-century America; (2) Present day America; and (3) Present Day India, Nigeria, or Brazil (select one).
In present day United States culture, childhood is a nurturing time of carefree exploration and personal development, where a child’s main job is to go to school. However, this was not always the way we understood youth and childhood in the U.S., and it is not how it is understood across all countries. In fact, the concept of childhood is linked closely to social class identities. In other words, in societies (or families) that have more socioeconomic resources, childhood is a time period set aside for parental nurturing, carefree exploration, and personal development. On the other hand, in contexts of severe economic hardships, childhood is a luxury that many families cannot afford. Instead, children enter the labor force at a much younger age as a necessity of family survival (Barone 2015).
Explore the ways that the social identity of “youth” and the category of “childhood” vary across the three social contexts mentioned above by incorporating photos of the expected jobs of young people in each context. Using your selected photos and assigned readings (e.g., course text, resources provided below, supplemental materials provided by your instructor, and two additional scholarly sources), create a 12-slide PowerPoint presentation (including one title slide and one references slide in APA style).
Your PowerPoint presentation should include two main parts:
Seven of your slides must contain photos with brief descriptions. Be sure to include a minimum of three photos for each of the three social contexts (you can include multiple photos per slide). You must obtain photos from public Internet searches and properly cite each photo.
In your description of each photo, be sure to:
Describe how the photo helps you understand the expectations and value of “youth” and “childhood” in that society. In other words, what clues does the photo give you to determine how the identity of youth is constructed in that society?
In the remaining three slides, address the following questions:
Explain how the identity of “youth” and the time period of “childhood” is socially constructed and how it varies over time and across countries. Explain how social class impacts the social construction of “youth” and “childhood.” Discuss how comparing the different photos across your three social contexts help you understand the ways in which these categories are socially constructed.
