Question

How far do professional golfers drive a ball? (For non-golfers, the drive is the shot hit from a tee at the start of a hole and is typically the longest shot.) Here’s a histogram of the average driving distances of the 190 leading professional golfers by May 5, 2013, along with summary statistics (www.pgatour.com).
a) Find a 95% confidence interval for the mean drive distance.
b) Interpreting this interval raises some problems. Discuss.
c) The data are the mean driving distance for each golfer. Is that another concern in interpreting the interval?
