Question

For each of the following hypothesis tests, find the P-value. (a) Researchers perform a hypothesis test with hypotheses Ηρ: μ =79 and Ηα: μ <79. From a sample of size n =27 they obtain a test statistic of t =-1.43. What is the corresponding P-value? Round to 4 decimal places. P = 0.0805 X (b) Researchers perform a hypothesis test with hypotheses Ηρ: μ =64 and Η: μ ≠64. From a sample of size n =22 they obtain a test statistic of t =-0.64. What is the corresponding P-value? Round to 4 decimal places. P = 0.5308 X (c) Researchers perform a hypothesis test with hypotheses Ηο: μ =79 and Ηα: μ +79. From a sample of size n = 13 they obtain a test statistic of t =1.76. What is the corresponding P-value? Round to 4 decimal places. P = 0.1471 X (d) Researchers perform a hypothesis test with hypotheses Ηο: μ =87 and Η: μ >87. From a sample of size n = 19 they obtain a test statistic of t =2.23. What is the corresponding P-value? Round to 4 decimal places. P = 0.014 X
