2. Find the p-values for the following hypothesis tests when the sample size is large and the population
standard deviation is known: (4 points each)
(a) H0: u = 100; H0: u =/ (doesnt equal) 100, where the test statistic equals 1.76 for the sample.
(b) H0: u = 37.1; H0:u =/ (doesnt equal) 37.1, where the test statistic equals -2.38 for the sample.
(c) H0: u >_ 12.5; H0: u < 12.5, where the test statistic equals -0.98 for the sample.
