He chooses a random sample of games and finds the mean number of runs allowed per game and the standard deviation in then number of runs per game allowed by each team. The data is recorded in the table below. Number of games Mean number of runs per game allowed Standard deviation in the number of runs per game allowed Boston Red Sox 35 3.96 1.07 New York Yankees 32 4.25 1.15 At the 0.05 level of significance, test the claim that the mean number of runs allowed per game by the Boston Red Sox is less than the mean number of runs allowed per game by the New York Yankees. 1. Which of the following would be the correct null and alternative hypothesis for this problem? [null] a. Ho:

In a recent sample, however, of a random sample of 55 fish caught from the lake, the mean length was 18.5 inches with a standard deviation of 3.2 inches. Can it beclaimed that the average length of a trout caught from Pyramid Lake is less than 19 inches? Use a significance level of α = 0.01. 1. Which of the following would be the correct null and alternative hypothesis for this problem? [null] a. Ho:
