The pass completion percentages of 10 college football quarterbacks for their freshman and sophomore seasons are shown in the table below. At \(\alpha = 0.10\), is there enough evidence to support the claim that the pass completion percentages have changed? Complete parts (a) through (b) below.### Player Data| Player | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 ||-----------------------------|-------|-------|-------|-------|-------|-------|-------|-------|-------|-------|| Completion percentage (freshman) | 68.3 | 62.1 | 56.3 | 59.0 | 62.1 | 51.0 | 60.8 | 54.9 | 57.1 | - || Completion percentage (sophomore)| 67.9 | 57.1 | 62.6 | 59.6 | 60.8 | 59.2 | 63.8 | 61.6 | 56.0 | 58.2 |#### (a) Null and Alternative Hypotheses:- The pass completion percentages have not changed.- Let \(\mu_d\) be the hypothesized mean of the differences in the pass completion percentages (freshman - sophomore). Determine the hypotheses:- A. \( H_0: \mu_d \ge 0 \) \( H_a: \mu_d < 0 \)- B. \( H_0: \mu_d = 0 \) \( H_a: \mu_d \ne 0 \)- C. \( H_0: \mu_d \ne 0 \) \( H_a: \mu_d = 0 \)- D. \( H_0: \mu_d \ge d \) \( H_a: \mu_d < d \)- E. \( H_0: \mu_d \le d \) \( H_a: \mu_d > d \)- F. \( H_0: \mu_d \le 0 \) \( H_a: \mu_d > 0 \)Correct answer: **B.

Is the average time to complete an obstacle course different when a patch is placed over the right eye than when a patch is placed over the left eye? Thirteen randomly selected volunteers first completed an obstacle course with a patch over one eye and then completed an equally difficult obstacle course with a patch over the other eye. The completion times are shown below. "Left" means the patch was placed over the left eye and "Right" means the patch was placed over the right eye.
