Use the information below to answer Questions # 37 - 42. The pass completion percentages of 10 college football quarterbacks for their freshman and sophomore are shown in the table below. At a = 0.01, is there enough evidence to support the claim that the pass completion percentages have changed? Assume the samples are random and dependent, and the population is normally distributed. Player: 1 2 3 4 5 6 7 10 Completion % (Freshman): 67.4 61.5 56.2 61.0 63.5 51.0 58.0 62.4 56.4 57.2 Completion % (Sophomore): 66.9 57.5 63.0 62.3 61.9 58.7 63.4 61.4 58.2 59.1 Let Ha be the hypothesized mean of the difference between pass completion percentages (freshman - sophomore). Write the claim mathematically and identify the null and the alternative hypotheses. Choose the correct answer below.
