Question

Hitting the fairway. One statistic used to assess professional golfers is driving accuracy, the percent of drives that land in the fairway. In 2009, driving accuracy for PGA Tour professionals ranged from about 50% to about 75%. Phil Mickelson, the third-highest money winner on the PGA Tour in 2009, hits the fairway only about 52% of the time.5 Phil is also one of the longest drivers on the tour, and increased distance is generally associated with decreased accuracy. (a) Phil hits 14 drives in a round. What assumptions must you make in order to use a binomial distribution for the count X

Answer 1

one assumption you must make is that the events are independent, that is, that the probability he hits the fairway in any one shot is the same for all the shots, and not dependent on the previous ones.

it is an assumption, and frankly a rather bad one

Answer 2

Which of these assumptions is least realistic?

And thank you!
