Suppose you are testing a hypothesis for a sample of 25 people for the null hypothesis H0: m … 85 versus the alternative hypothesis Ha: m 7 85. The population standard deviation is unknown and the test results into a p@value = .0292. NW

a. Justify why the t-statistic would be more suitable for this test.

b. Make an appropriate conclusion about the test at a 5% significance level.

c. Determine the p-value if this test were to be conducted for a two-tailed test with Ha: m ≠ 85 and make a conclusion at the 5% significance level. Applying the Concepts—Basic
