lume in The following numbers are the differences in pulse rate (beats per minute) before and after running for 12 randomly selected people. Positive numbers mean the pulse rate went up. Test the hypothesis that the mean difference in pulse rate was more than 0, using a significance level of 0.05. Assume the population distribution is Normal. 22, 11, 14, 10, 13, 7, 0, 2, 12, 41, 0, and 12 O Determine the null and alternative hypotheses. Choose the correct answer below.
