After doing a chest x-ray, your doctor says the results are inconclusive. So, you are put on a six-month course of isoniazid to be safe. About six months later, while sitting in your medical microbiology class during a lecture on tuberculosis, you suddenly realize why you had that positive reaction to the skin test six months earlier. It had nothing to do with being infected, but was because you were born in Norway and your family moved to the United States when you were four years old.

3. What is going on here? Discuss in detail. 4. A while later, you told a friend of yours who is HIV-positive about your TB scare. She said that her doctor doesn't typically use the TB skin test on her, even though people with HIV are more susceptible to TB. Why is the skin test not always a reliable TB test for those with HIV?

A simple random sample of

60

adults is obtained from a normally distributed? population, and each? person's red blood cell count? (in cells per? microliter) is measured. The sample mean is

5.24

and the sample standard deviation is

0.51

Use a

0.01

significance level and the given calculator display to test the claim that the sample is from a population with a mean less than

5.4

which is a value often used for the upper limit of the range of normal values. What do the results suggest about the sample? group?

You collect data to answer the research question, “Are high school boys involved in more automobile accidents than high school girls?” After conducting a hypothesis test, you conclude that there is sufficient evidence to reject the null hypothesis at α = 0.05. Use complete sentences to answer the following.

a. What were your null and alternative hypotheses in words?

b. State your conclusion pertaining to real-life in words.

c. If this conclusion is actually NOT correct, what type of error is this? State the correct conclusion in words.

d. What are some possible consequences of this error?

e. How might you change the alpha level to reduce this type of error? Explain.

A random sample of 9 recently sold homes in a local market collects the list price and selling price for each house. The prices are listed below in thousands of dollars. A group of realtors wants to test the claim that houses are selling for more than the list price.

(a) Find d¯, the mean of the differences.

(b) State the claim, the negation of the claim, H₀, and H₁ (using equations and the parameter μd).

(c) Find the p-value. Use a significance level of α=.05 to test the claim. State your conclusion about H_0.

(d) State your conclusion about the original claim.

Consider an automated plagiarism detection software that is used to evaluate essay submissions. Four sections of a writing course use the software to check for plagarism, with 30% of the students in section 1, 16% in section 2, 30% in section 3, and 24% in section 4. In section 1 of a course, 20% of the essays are flagged, in section 2, 23%, section 3, 15% and section 4, 8%. (a) What percentage of total students committed plagiarism overall? (b) Given that a particular student committed plagiarism, what in the probability that they were registered for section 1 of the course. (c) Given that a particular student committed plagiarism, what in the probability that they were registered for section 2 of the course. (d) If there are 200 students registered between these 4 sections, how many students in section 3 cheated?
