8. Gravetter/Wallnau/Forzano, Essentials - Chapter 11 - End-of-chapter question 16 A repeated-measures study with a sample of n = 5 participants produces a mean difference of Mp = 4 with SS= 30. Use a two-tailed hypothesis test with a = .05 to determine whether this sample provides evidence of a significant treatment effect. t-critical t
O Failure to reject the null hypothesis; there is not a significant treatment effect. Rejection of the null hypothesis; there is a significant treatment effect. Failure to reject the null hypothesis; there is a significant treatment effect. Rejection of the null hypothesis: there is not a significant treatment effect. Now assume that the sample standard deviation is 55 = 480 and repeat the hypothesis test. t-critical t Rejection of the null hypothesis; there is a significant treatment effect. Failure to reject the null hypothesis: there is a significant treatment effect. O Failure to reject the null hypothesis; there is not a significant treatment effect. Rejection of the null hypothesis; there is not a significant treatment effect. Explain how sample variability influences the likelihood of finding a significant mean difference. Low sample variability the likelihood of rejecting the null hypothesis if the null hypothesis is false.
