Extracted text: 1.) In a statistics class, students took their pulses before and after being frightened. The frightening event was having the teacher scream and run from one side of the class to the other. The pulse rates (beats per minute) are shown in a.) Test the hypothesis that the mean student pulse rate is higher after a fright using a = 0.05. 64 68 68 100 68 60 After 80 60 92 80 68 84 80 80 68 112 76 72 84 68 104 92 72 88 80 92 I. State your hypotheses II. State the allowable type I error rate (a) III. Calculate your test statistic, the p-value and draw the physical representation of the p-value V. Make your decision to either reject the null or fail to reject the null. Make a concluding statement. b.) Run a 95% confidence interval for the hypothesis test above. Don't forget to make a proper conclusion.
