The following statistics are calculated by sampling from four normal populations whose variances are equal: (You may find it useful to reference the t table and the q table.) x1 = 136, n1 = 6; x2 = 145, n2 = 6; x3 = 135, n3 = 6; x4 = 130, n4 = 6; MSE = 57.1 a. Use Fishers LSD method to determine which population means differ at = 0.05. (Negative values should be indicated by a minus sign. Round final answers to 2 decimal points.) b. Use Tukeys HSD method to determine which population means differ at = 0.05. (If the exact value for nT c is not found in the table, then round down. Negative values should be indicated by a minus sign. Round your answers to 2 decimal places.) c. Do all population means differ? multiple choice No, only some of the population means differ. Yes, all population means differ. No, none of the population means differ
