Question
Consider a drug testing company that provides a test for marijuana usage. Among 348 tested subjects, results from 28 subjects were wrong (either a false positive or a false negative). Use a 0.10 significance level to test the claim that less than 10 percent of the test results are wrong. Identify the null and alternative hypotheses for this test. Choose the correct answer below. O A. H,: p=0.1 H,:p>0.1 OB. H,: p<0.1 H,:p=0.1 OC. H: p=0.1 H,: p#0.1 OD. H,: p=0.1 H,:p<0.1 Identify the test statistic for this hypothesis test. The test statistic for this hypothesis test is (Round to two decimal places as needed.) Identify the P-value for this hypothesis test. The P-value for this hypothesis test is (Round to three decimal places as needed.) Identify the conclusion for this hypothesis test. O A. Fail to reject H. There is not sufficient evidence to warrant support of the claim that less than 10 percent of the test results are wrong. O B. Reject Hg. There is sufficient evidence to warrant support of the claim that less than 10 percent of the test results are wrong. OC. Fail to reject H. There is sufficient evidence to warrant support of the claim that less than 10 percent of the test results are wrong. O D. Reject Hg. There is not sufficient evidence to warrant support of the claim that less than 10 percent of the test results are wrong.

A data set includes data from student evaluations of courses. The summary statistics are n= 89, x= 3.85, s= 0.51. Use a 0.05 significance level to test the claim that the population of student course evaluations has a mean equal to 4.00. Assume that a simple random sample has been selected. Identify the null and alternative hypotheses, test statistic, P-value, and state the conclusion that addresses the original claim. -... What are the null and alternative hypotheses? Ο Β.

Determine the P-value (Round to three decimal places as needed.) State the final conclusion that addresses the original claim. Ho. There is V evidence to conclude that the mean of the population of student course evaluations is equal to 4.00 V correct.
