A typical round of golf takes approximately 3.5 hours (walking, without an electric cart). Many weekend golfers take more time as a result of lost golf balls, thinking about certain shots, and talking to other players. The manager at the Wawona Golf Course in Wawona, California, obtained a random sample of round times (in hours), and the data are reported in the table below.
a. Construct a stem-and-leaf plot for these data.
b. Compute the ratio IQR/s.
c. Construct a normal probability plot for these data.
d. Is there any evidence to suggest these data are from a non-normal population? Justify your answer.
