I need part a b and c to this question please and thank you!

Scores In the first and fourth (final) rounds for a sample of 20 golfers who competed In golf tournaments are shown In the following table. First Final First Final Play tound Round Player Round Round Golfer 1 70 7 Golfer 11 72 72 Golfer 2 71 Golfer 12 70 Golfer 3 70 Golfer 13 70 73 Golfer 72 71 Golfer 14 70 77 Golfer S 70 Golfer 15 65 70 67 Golfer 16 65 Golfer 7 71 Golfer 17 71 70 Golfer B 6B Golfer 18 68 Golfer 9 57 73 Golfer 19 69 Golfer 10 70 Golfer 20 67 71 Suppose you would like to det he first round of a golf toumar significantly different than the mean score for the fourth and 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 d (a) Lise a - 0.10 to test for a statistically significantly difference between the population means for first- and fourth-round scores. State the null and alternative hypotheses. (Use p = mean score first round - mean score fourth round.) OHOp.o OHH SO Calculate the value of the test statistic. (Round your answer to three decimal places.) Calculate the p-value. (Round your answer to four decimal places.) -value - State your conclusion. O Do not Reject He There is sufficient evidence to conclude that the mean score for the first on score for the fourth and final round. O Do not reject Ho- Th mean score for the fourth and final round Q Reject Hy. There is sufficient evidence to condude that the mean score for the first round of a golf tournament is significantly different than the mean score for the fourth and final round. O Reject Her There is insufficient evidence to condude that the mean score for the first round of a golf tournament is significantly different than the mean score for the fourth and final round (b) What is the point estimate of the difference between the two population means? (Use mean score first round - mean score fourth round.) For which round is the popu O The mean of the first round er than the mean of the fourth round scores. (c) what is the margin of error for a 90% confiden Interval estimate for the difference bet to two decimal places
