A simple random sample of 30 male golfers and another simple random sample of 45 female golfers will be taken.
a. Show the sampling distribution of for male golfers.
b. What is the probability that the sample mean is within 3 strokes of the population mean for the sample of male golfers?
c. What is the probability that the sample mean is within 3 strokes of the population mean for the sample of female golfers?
