The following statistics are calculated by sampling from four normal populations whose variances are equal: (You may find it useful toreference the ttable and the g table.)= 137, n₁ = 4; 2 = 148, n₂ = 4; 3 = 142, n3 = 4; 4 = 135, n4 = 4; MSE = 46.6a. Use Fisher's LSD method to determine which population means differ at a = 0.05. (Negative values should be indicated by a minussign. Round final answers to 2 decimal points.)Population MeanDifferencesH1-H2H1 H3H₁-H4H2 H3H2-H4H3 H4[[[1Confidence Interval1]Can we conclude that thepopulation means differ? b. Use Tukey's HSD method to determine which population means differ at a = 0.05. (If the exact value for n-c is not found in thetable, then round down.

To test whether the mean time needed to mix a batch of material is the same for machines produced by three manufacturers, the Jacobs Chemical Company obtained the following data on the time (in minutes) needed to mix the material. Compute the values below (to 2 decimals, if necessary). Sum of Squares, Treatment Sum of Squares, Error a. Use these data to test whether the population mean times for mixing a batch of material differ for the three manufacturers. Use a = 0.05.
