I need to know how to answer the question without using excel or code. 5. Scores in the first and fourth (final) rounds for a sample of 20 golfers who competedin PGA tournaments are shown in the following table. Suppose you would like todetermine if the mean score for the first round of a PGA Tour event is significantlydifferent than the mean score for the fourth and final round. Does the pressureof playing in the final round cause scores to go up? Or does the increased playerconcentration cause scores to come down?FinalRoundFinalRoundFirstFirstPlayerRoundPlayerRoundMichael LetzigScott VerplankD. A. PointsJerry KellySoren HansenD. J.
