A male student of the author has a measured pulse rate of 52 beats per minute. According to a National Center for Health Statistics data set, males have a mean pulse rate of 67.3 beats per
minute and a standard deviation of 10.3 beats per minute. Determine whether the student's
pulse rate is significantly low or high by determining the difference between the student's
pulse rate and the mean pulse rate of males and how many standard deviations that difference
represents by calculating the z score. Consider usual pulse rates to be within 2 standard
deviations of the mean.
