The following numbers are the differences in pulse rate (beats per minute) before and after running for 12 randomly selected K 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, 9, 11, 11, 16, 8, 0, 0, 12, 38, 1, and 15 - - . OA. HO H 0 Ha : H#0 OD. Ho: H#0 OE. Ho: H= 0 OF. HO: H > O Ha - H = 0 Ha: H 0 Ha H # 0 OD. HO H#0 OE.
