Since the p-value is (greater than or less than or equal to) the significance level, (do not reject or reject) H0. There is (insufficient or sufficient) evidence to conclude that the population mean is more than 0 beats per minute at a significance level of 0.05.
 

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. 21, 9, 10, 12, 16, 10, 0, 3, 9, 39, 1, and 12 Determine the null and alternative hypotheses. Choose the correct answer below. OA. Ho: 0 Ha: = 0 O B. Ho: >0 Ha:0 OC. Ho: 0 Ha: #0 Ha: H
