Hypothesis Testing Using a P -Value In Exercises 31–36, (a) identify the claim and state H 0 and H a . (b) find the standardized test statistic z. (c) find the corresponding P-value. (d) decide whether to reject or fail to reject the null hypothesis. (e) interpret the decision in the context of the original claim. 33. Boston Marathon A sports statistician claims that the mean winning times for Boston Marathon women’s open division champions is at least 2.68 hours. The mean winning time of a sample of 30 randomly selected Boston Marathon women’s open division champions is 2.60 hours. Assume the population standard deviation is 0.32 hour. At α = 0.05, can you reject the claim? (Source: Boston Athletic Association)
