Given an expected mean of u= 33, if a treatment produces a sample mean of M = 25 with sm = 5 among a sample of n = 30, which t-statistic should be obtained and which decision should be made if conducting a two-tailed hypothesis test with a = .05 - 1.6 and fail to reject the null -1.6 and reject the null - 2.045 and reject the null 0 - 2.045 and fail to reject the null

The F test (ANOVA) is designed to analyze multiple IVS all of the above interaction between variables multiple levels of one IV

For a repeated measures t test with a sample of n = 25 participants, the two-tailed critical region at a = .01 would have boundaries of O t - +2.797 O t = +2.110 O t = +2.787 O t = +2.064
