b) If a person tests negative for the virus, what is the probability that the person really is not infected.(This is called the "negative predictive value")c) Examine the "Infected" column of the table. If a person is actually infected, what is the probability thattheir test will be positive?(This is called test's "sensitivity")d) If a person is actually not infected, what is the probability that their test will be negative?%(This is called the test's "specificity") A certain affects virus 0.4% of the population (in a population of 100,000 people, 400 will be infected withthe virus). A test used to detect the virus in a person is positive 87% of the time if the person has the virus(true positive) and it is positive 14% of the time if the person does not have the virus (false positive).

Use the following information for the question. A group of home gardeners want to test whether the type of soil used to grow heirloom tomatoes has an effect on the number of tomatoes harvested. Gardeners randomly assigned tomato plants to be grown in soil with no fertilizer, commercial plant food, and homemade compost. All other growing conditions were kept the same. Forty plants were assigned to each group. At the end of the growing season the number of tomatoes harvested was counted. Assume that all other conditions for the ANOVA test have been met.State the null and alternative hypothesis.

Use the information below to answer questions 27 and 28. Consider again the NCHS-reported mean total cholesterol level in 2002 for all adults is 2003. Suppose a new drug is proposed to lower total cholesterol. A study is designed to evaluate the ecacy of the drug in lowering cholesterol. Fifteen patients are enrolled in the study and asked to take the new drug for 6 weeks. At the end of 6 weeks, each patient’s total cholesterol level is measured and the sample statistics are as follows:n = 15, x̄ = 195.9, and s = 28.7. Is there statistical evidence of a reduction in mean total cholesterol in patients after using the new drug for 6 weeks? 27.
