Chapter 9.2, Problem 26E
Using P-Values to Reject or Not Reject. In Exercises 21–32, use Table A-1 to find the P-value that corresponds to the given standard score, and determine whether to reject the null hypothesis at the 0.05 significance level. Is the alternative hypothesis supported?

State whether the standardized test statistic t indicates that you should reject
the null hypothesis. Explain.
(a) t = -2.272
(b) t = 2.154

Final Conclusions. In Exercises 25–28, use a significance level of α = 0.05 and use the given information for the following:
a. State a conclusion about the null hypothesis. (Reject H0 or fail to reject H0)
b. Without using technical terms or symbols, state a final conclusion that addresses the original claim.
Original claim: The standard deviation of pulse rates of adult males is more than 11 bpm. The hypothesis test results in a p-value of 0.3045.
