Introduction to Hypothesis Testing
Assignment Overview
Suppose that a 2012 National Health Interview Survey gives the number of adults in the United States which gives the number of adults in the United States (reported in thousands) classified by their age group, and whether or not respondents have ever been tested for HIV. Here are the data:
Age Group
Tested
Never Tested
18-44 years
50,080
56,405
45-64 years
23,768
48,537
65-74 years
2,694
15,162
75 years and older
1,247
14,663
Total
77,789
134,767
Case Assignment
Discuss probability. What is its history? What is the theory of probability? How is it calculated? What are the advantages and disadvantages of using this technique?
Identify and discuss the two major categories of probability interpretations, whose adherents possess conflicting views about the fundamental nature of probability.
Based on this survey, what is the probability that a randomly selected American adult has never been tested? Show your work. Hint: using the data in the two total rows, this would be calculated as p (NT) /( p (NT) + p (T)), where p is probability.
What proportion of 18- to 44-year-old Americans have never been tested for HIV? Hint: using the values in the 18-44 cells, this would be calculated as p (NT) / ( p (NT) + p (T)), where p is probability. Show your work.

Additional considerations to keep in mind while working on your Case Assignments:
Originality and Use of directly quoted material
The purpose of each assignment is for you to present your understanding and synthesis of the background material and key concepts. Accordingly, this must be accomplished substantially in your own words.
Use directly quoted material sparingly and only when preserving the exact words of an author is necessary. For purposes of this course, rarely should directly quoted material represent more than 5 percent to 10 percent of your entire case paper- content. Composing a paper patched together from mostly quoted material is not acceptable.
Be sure to properly reference all directly quoted material and include the in-text citations. All paraphrased information also requires reference citations at the end of the paraphrased section.
