A)Let H be the hypothesized mean of the differences in the pass completion percentages (freshman - sophomore). Then d is the sample mean of the differences. What are Ho and H? B) Calculate d andSd. Calculate d. d =.......... (Round to three decimal places as needed.) Calculate SdSd..........=(Round to three decimal places as needed.)(c) Find the standardized test statistic t. T= .........(Round to two decimal places as needed.) (d) Calculate the P-value. P-value =........... (Round to three decimal places as needed.) (e) The rejection regions for this test would be t3.250, 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?.........the results......... the same as using the critical value approach .........the null hypothesis. There is ........enough evidence to the claim V the results V the same as using the critical value approach. that the pass completion percentages have........

The pass completion percentages of 10 college football quarterbacks for their freshman and sophomore seasons 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? Complete parts (a) through (e) below. Player LO CO CO Completion percentage (freshman) 68.4 61.5 56.7 61.0 63.9 51.0 58.0 63.4 55.6 58.5 Completion percentage (sophomore) 68.2 57.5 63.5 61.8 62.2 59.2 63.5 62.4 57.3 61.4 (a) Identify the claim and state Ho and Ha- What is the claim?
