The following statistics are computed by sampling from three normal populations whose variances are equal: (You may find it useful to reference the table and the g table.) X130.7, n₁ = 7; X2 = 36.9, n2 = 8; X3 = 42.9, n3 = 4; MSE = 29.0 a. Calculate 95% confidence intervals for H1 - H2. H1 H3, and u2 - u3 to test for mean differences with Fisher's LSD approach. (Negative values should be indicated by a minus sign. Round final answers to 2 decimal points.) Population Mean Differences H₁-4₂ H₁ H3 P/₂-4/3 Confidence Interval -12.06 -9.01 Can we conclude that the population means differ? Yes Yes No
