The following statistics are computed by sampling from three normal populations whose variances are equal: Use Table 2 and Table 5.formula225.mml = 19.8, n1 = 4;formula226.mml = 24.0, n2 = 10;formula227.mml = 28.0, n3 = 6;MSE = 27.8
a. Use Fisher’s LSD test to determine which population means differ at 95% confidence intervals. (Negative values should be indicated by a minus  sign. Round your answers to 2 decimal places.)

b. Repeat the analysis with Tukey’s HSD approach. (If the exact value for nT – c is not found in the table, use the value which is closer.
Negative values should be indicated by a minus sign. Round your answers to 2 decimal places.)
