5. A certain virus infects 17% of people. A test used to detect the virus in a person is positive 96% of the time if the person has the virus and 4% of the time if the person does not have the virus. a. For a sample of 20,000 people complete the table below. The first entry has been completed for you. Test Result Totals Positive Negative Has Virus 96 x 3400 = 3264 Does Not Have Virus Totals 20,000 b. Find the probability that a person has the virus given that they have tested positive. C. Find the probability that a person does not have the virus given that they test negative. d. If two people are chosen at random, find the probability that at least one of them has the virus.

A consumer products testing group is evaluating two competing brands of tires, Brand 1 and Brand 2. To do this, the group chooses 15 cars at random and installs both brands on each car. After all of the cars are driven over the standard test course for 20,000 miles, the amount of tread wear (in inches) on each brand of tire on each car is recorded. The data and the differences (Brand 1 minus Brand 2) are shown in the table below. Car Brand 1 Brand 2 Difference (Brand 1- Brand 2) Send data to calculator V 1 Lower limit: Upper limit: 0.25 0.97 2 0.28 0.40 0.59 3 4 X 0.24 5 0.33 6 S 0.26 0.17 0.52 0.08 0.35 7 0.27 0.48 8 9 0.35 0.22 0.12 0.86 10 0.28 1.19 11 12 13 0.35 0.27 0.28 0.35 0.03 0.82 14 15 0.25 0.26 -0.72 -0.31 0.05 0.07 -0.19 0.18-0.21 0.23 -0.64 -0.91 -0.01 -0.47 0.32 -1.02 -0.82 Assume that the population of these differences in tread wear (Brand 1 minus Brand 2) is approximately normally distributed.

A Survey was conducted of newlyweds in a country who have a spouse of a different race or ethnicity from their own. The survey included random samples of 1000 newtyweds in Ethnicity A and 1000 newlyweds in Ethnicity B. In the survey, 13% of respondents of a different race or ethnicity from their own is less than the proportion of newlyweds in Ethnicity B that have a spouse of a different race or ethnicity from their own? Ethnicity A and 24% of respondents in Ethnicity B had a spouse of a different race or ethnicity from their own. At a = 0.01, is there evidence to support the claim that the proportion of newlyweds in Ethnicity A who have a spouse Let p, represent the proportion of newlyweds in Ethnicity A who have a spouse of a different race or ethnicity from their own.

You are a customer support manager at Apple. Your staff are rated by the customer after each support call they close. Each month you randomally sample the cases of each employee and if you find sufficient "Perfect" cases then you give the employee a $250 award. This month you give the award if you find (at least) 4 Perfect cases. Suppose an employee handled 42 cases of which 7 are Perfect cases and 35 are not. Assume you sample 10 of the cases of that employee. Answer the following: a. What is the probability that you will find no Perfect cases? nothing. (Round to four decimal places as needed.) b. What is the probability that there will be at least 1 Perfcet case? (Round to four decimal places as needed.) c. What is the probability that there will be 4 Perfect cases? (Round to four decimal places as needed.) d. What is the probability that the award will not be given? (Round to four decimal places as needed.)
