Question
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 g table.) al = 156, n1 = 5; a2 = 161, ng = 5; 3 = 150, n3 = 5; x4 = 141, n4 = 5; MSE = 44.3 a. Use Fisher's LSD method to determine which population means differ at a = 0.05. (Negative values should be indicated by a minus sign. Round final answers to 2 decimal points.) Population Mean Differences Can we conclude that the population means differ? Confidence Interval P1 - 42 1 - 13 P1- H4 P2 - P3 H2 - H4 P3 - 44 b. Use Tukey's HSD method to determine which population means differ at a = 0.05. (If the exact value for m -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.) Population Mean Differences Can we conclude that the Confidence Interval population means differ? H1 - 42 P1 - P3 P1 - H4 P3 - P4 c. Do all population means differ? O No, only some of the population means differ. O Yes, all population means differ. O No, none of the population means differ.
