Females–Pulse Rates before and after a Fright In a statistics class taught by one of the authors, students took their pulses before and after being frightened. The frightening event was having the teacher scream and run from one side of the room to the other. The pulse rates (beats per minute) of the women before and after the scream were obtained separately and are shown in the table. Treat this as though it were a random sample of female community college students. Test the hypothesis that the mean of college women’s pulse rates is higher after a fright, using a significance level of 0.05. See page 493 for guidance.
