The following numbers are the differences in pulse rate (beats per minute) before and after running for 6 randomly selected people. Positive numbers mean the pulse rate went up: 24, 12, 14, 12, 16, 10. Test the hypothesis that the mean difference in pulse rate was more than 0, using a significance level of 0.05. Assume the population is Normally distributed. a) State the hypotheses. b) give the resulting t-statistic and p-value. c) use the p-value to make a conclusion about whether or not to favor the null hypothesis. State your conclusion in the context of the problem.
