Assume that matched pairs of data result in the given number of signs when the value of the second variable is subtracted from the corresponding value of the first variable. Use the sign test with a 0.05 significance level to test the null hypothesis of no difference. Positive signs: 172; negative signs: 439; ties: 0 (from challenges to referee calls in the most recent U.S. Open tennis tournament)

ANSWER:Solution 8BSC Step 1 By assuming that matched pairs of data result in the given number of signs when the value of the second variable is subtracted from the corresponding value of the first variable. We use the sign test with a 0.05 significance level to test the null hypothesis of no difference. The Hypotheses can be expressed as H0 There is no difference between challenges to referee calls in the most recent U.S. Open tennis tournament. H1 There is a difference between challenges to r
