Step 4: Because all conditions are met, it is appropriate to use the paired samples t test to analyze these data. Run the paired samples t test on this data set to determine whether there is a difference in time to descend 800 ft when the propeller is windmilling versus when the propeller is stopped and report the results below. Set the significance level at α = 0.05. The hypothesis statement is Ho: Md = Ha: Md Degrees of freedom for this test: df = 25 Mean of the differences (rounded to two decimal places): X = 5.92 Standard error of the mean (rounded to two decimal places): = 1.08 sd √n Compute the test statistic using the rounded values above. Report the test statistic. (Round your answer to two decimal places.) хо-на $d √n The P-value for this test statistic (rounded to two decimal places) is 0.00 seconds = 5.49 Step 5: Because the P-value is less decision of reject the null hypothesis. There is in time to descend 800 ft when the propeller is windmilling versus when the propeller is stopped. Step 6: Create a 98% confidence interval for the difference in time to descend 800 ft. The t critical value for this confidence interval based on 25 degrees of freedom and rounded to three decimal places is than the significance level, a = 0.05, this hypothesis test leads to a convincing evidence that there is a difference Lower limit (rounded to two decimal places) is Upper limit (rounded to two decimal places) is Based on this analysis, we are % confident that the actual difference in time to descend 800 ft is somewhere between and seconds. Because both endpoints of the interval are positive, this indicates that the mean time to descend 800 ft when the propeller is stopped is greater than when the propeller Trial 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 Windmilling 73.4 68.9 74.1 71.7 74.2 63.5 64.4 60.9 79.5 74.5 76.5 70.3 71.3 72.7 64.2 67.5 71.2 75.6 73.1 77.4 77 77.8 77 72.3 69.2 63.9 70.3 Stopped 82.3 75.8 75.7 71.7 68.8 74.2 78 68.5 90.6 81.9 72.9 75.7 77.6 174.3 82.5 81.1 72.3 77.7 82.6 79.5 82.3 79.5 79.7 73.4 76 74.2 79
