Question

1. A golf coach suggests that altering your grip will result in greater distances in your drive. You test their theory with the help of five of your friends. The results in the table below show the average drive for each golfer using the old and the new golf grip.

Drive Distance (in yards)

Swing / Golfer	1	2	3	4	5	6
Old	228	245	254	255	240	278
New	240	250	257	265	255	269

If the calculation for the differences between the scores is "new grip-old grip", identify the alternative hypothesis to test this claim:
a) Ha: u_D < 0
b) Ha: u_N - u_O > 0
c) Ha: u_D > 0
d) Ha: u_N - u_O ≥ 0

2. Calculate the average difference (round your answer to two decimal points)

3. Calculate the Test Statistic (round your answer to two decimal places)

4. Identify the confidence coefficient for this hypothesis test if the significance level is set as 0.01. Your answer should have 3 decimal places
