Scores in the first and fourth (final) rounds of a sample of 20 golfers who competed in PGA tournaments are shown in the file GolfScores. Suppose you would like to determine if the mean score for the first round of PGA Tour event is significantly different than the mean score of the fourth (final) round. Does the pressure of playing in the final round cause scores to go up? Or does the increased player concentration cause scores to come down?
Set your hypothesis to test if there is difference in the mean scores of the first and fourth rounds.
Use α= .10 to test for a statistically significant difference between the population means for first- and fourth-round scores. What is the p-value? What is your conclusion?
Will your conclusion in a) change if α = 0.05?
