The pass completion percentages of 10 college football quarterbacks for their freshman and sophomore seasons are shown in the table below. At a 0.05, is there enough evidence to support the claim that the pass completion percentages have changed? Complete parts (a) through (e) below 1 2 3 4 5 6 7 8 9 10 67.4 62.1 57.1 60.0 64.8 50.0 58.0 64 3 55.3 59.9 67.3 58.1 62.8 60.6 63.3 57.6 63.1 63.3 56.9 61 4 Player Completion percentage (freshman) Completion percentage (sophomore) (d) Calculate the P-value P-value = 3.03 (Round to three decimal places as needed.) (e) The rejection regions for this test would be t<-2 262 and 1>2.262, so the null hypothesis would not be rejected. Decide whether to reject or fail to reject the null hypothesis using the P-value. Interpret the decision in the context of the original claim. Are the results the same as the critical value approach? Reject the null hypothesis. There is not enough evidence to support the claim Yes, the results are the same as using the critical value approach. that the pass completion percentages have increased.
