![o Consider data from Problem 4.59
To understand better the effects of exercise and
aging on various circulatory functions, the article “Cardiac
Output in Male Middle-Aged Runners" (Journal of Sports
Medicine [1982]: 17–22) presented data from a study of
21 middle-aged male runners. The following data set gives
values of oxygen capacity values (in milliliters per kilo-
4.59
gram per minute) while the participants pedaled at a speci-
fied rate on a bicycle ergometer:
12.81 14.95 15.83 15.97 17.90 18.27 18.34
19.82 19.94 20.62 20.88 20.93 20.98 20.99
21.15 22.16 22.24 23.16 23.56 35.78 36.73
a. Compute the median and the quartiles for this data set.
b. What is the value of the interquartile range? Are there
outliers in this data set?
c. Draw a modified boxplot, and comment on the interest-
ing features of the plot.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Ffa5c2b4c-9f85-4543-bcf5-9f61871c8c68%2F06c0d192-bb29-4e9e-835d-34deed554671%2Frufjc9p_processed.jpeg&w=3840&q=75)
