Question

3. As with the previous homework, we want to compare the average decrease in PSI between the two teams. Create a new column for decrease in PST, defined as PST Pregarne minus PST_Halftime. Use "Analyze Fit Y by X", select the appropriate variables (see the notes if you have trouble with this), hit "OK", then select "t Test" from the drop down menu on the next screen. The results that you ignored in the previous homework are the results of interest for this homework a. What is the value of the test statistic testing Ho.,Patriots-Ngatts-O? 6.950814 b. What is the value of the numerator of this test statistic? .95750 c. What is the value of the denominator of this test statistic? .13776 d. What is the statistical decision resulting from this hypothesis test? pa0.05, so fail to reject the null and conclude that the difference in mean PSI decrease is statistically significant. p<0.05, so fail to reject the null and condude that the dirference in mean PSI decrease is statistically significant. p 0.05, so reject the null and conclude that the difference in mean PSI decrease is not statistically significant. p<0.05, so reject the nu and conclude that the difference in mean PSI decrease is not statistically significant. pc 0.05, so fail to reject the null and condudc that the difference in mean PSI decrease is not statistically significant. p0.05, so fail to reject the null and conclude that the difference in mean PSI decrease is not statistically significant. p0.05, so reject the null and conclude that the difference in man PSI decrease is statistically significant. p<0.05, so reject the null and conclude that the difference in mean PSI decrease is statistically significant.
