Refer to the heart rate distribution of Exercise 4.S.16. If we use the 1.5 × IQR rule, from Chapter 2, to identify outliers, how large would an observation need to be in order to be labeled an outlier on the upper end?
Exercise 4.S.16
Resting heart rate was measured for a group of subjects; the subjects then drank 6 ounces of coffee. Ten minutes later their heart rates were measured again. The change in heart rate followed a normal distribution, with a mean increase of 7.3 beats per minute and a standard deviation of 11.1
