a] State the null and alternate hypotheses. Also state if the test is left-tailed, right-tailed, or two-tailed. b] Find the P-value, and indicate how you obtained it. c] Write a comparison between your P-value and the α-value given. d] Decide whether to reject or accept the null hypothesis. e] Interpret the result as we did in class. (You could also answer this way: what does it mean in the context of the problem, or what should be done about these results? A 1995 study shows that since records were first kept in a meteorologist's hometown, the average temperature during the month of May was μ = 68 degrees. The meteorologist then looks up the average temperatures for each of the 25 Mays since then, and finds their sample mean to be x = 73 and their standard deviation to be s = 8.55 degrees. Can the meteorologist claim that the average temperature for May is different from how it used to be? Use a 1% level of significance.
