O Rejection of the null hypothesis; there is a significant treatment effect. O Failure to reject the null hypothesis; there is not a significant treatment effect. O Failure to reject the null hypothesis; there is a significant treatment effect. O Rejection of the null hypothesis; there is not a significant treatment effect. Now assume that the sample standard deviation is SS = 480 and repeat the hypothesis test. t-critical + 2.015 1.000 O Failure to reject the null hypothesis; there is not a significant treatment effect. O Rejection of the null hypothesis; there is not a significant treatment effect. O Failure to reject the null hypothesis; there is a significant treatment effect. O Rejection of the null hypothesis; there is a significant treatment effect. Explain how sample variability influences the likelihood of finding a significant mean difference. increases the likelihood of rejecting the null hypothesis if the null hypothesis is false. Low sample variability

ter question 13 A repeated-measures study with a sample of n = 6 participants produces a mean difference of MD = 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 + 2.571 2.000 t Distribution Degrees of Freedom = 21 5000 5000 -3.0 -2.0 -1.0 0.0 1.0 2.0 3.0 0.000
