Exercise 64 looked at distances PGA golfers can hit the ball. The standard deviation of these average drive distances is 11.2 yards, and the quartiles are Q1 = 282.05 yards and Q3 = 294.5 yards.
a) Write a sentence or two describing the spread in distances based on
i. The quartiles.
ii. The standard deviation.
b) Do you have any concerns about using either of these descriptions of spread?

Data From Exercise 64

The display shows the average drive distance (in yards) for 199 professional golfers during a week on the men’s PGA tour in 2015.

a) Describe this distribution.
b) Approximately what proportion of professional male golfers drive, on average, 280 yards or less?
c) Estimate the mean by examining the histogram.
d) Do you expect the mean to be smaller than, approximately equal to, or larger than the median? Why?
