It is commonly known that approximately 10% of the population is left-handed. Nike Golf would like to estimate the proportion of left-handed golfers in order to plan the schedule of golf club production. Assume Nike collected a sample of 200 golfers.

a. What is the probability that more than 12% of the golfers in the sample are left-handed?

b. What is the probability that less than 14% of the golfers in the sample are left-handed?

c. What is the probability that between 6% and 9% of the golfers in the sample are left-handed?

d. Suppose the sample that Nike collected had nine lefthanded golfers. What conclusions should Nike draw about the population of left-handed golfers?
