Use the sample results to test the hypothesis of no difference between the population mean 18-hole scores for the two golfers. (The mean value represents the numerical mean of the scores taken from the rounds of golf played, represented by N)

Palmer, 1960 Woods, 1999

Mean = 69.95 Mean = 69.56

N = 112 N = 84

a. Assuming a population standard deviation of 2.5 for both golfers, what is the value of the test statistic?

b. What is the p-value?

c. Using alpha = .01, what is your conclusion?

Write up your results, show the null and alternate hypotheses, set up the problem and show the test statistic.
