Answer . Explain why? (i). If the sample average of Group 1 is x, = 242.0, sample average of Group 2 is X2 = 246.4 and sample average of Group 3 is X3 = 228.8, at the level of significance a = 0.05, conduct the following post hoc test (assuming n = n2 = n3 = 5) 1. Ho: My = M2 VS H1 : My # H2 using Tukey-Kramer's procedure Critical value: Qal,n-1 = Test statistic: Q - stat = Q-stat Q-crit Reject HO or not? Meaning Group X1 Group X2 2. Ho: My - 0.5/2 - 0.5/3 = 0 vs H, : My - 0.5/2 - 0.5/ # 0, using Scheffe's procedure Critical value: (1 - 1) Fal-1,n-1 = Test statistic: Sstat = Page 3 of 8 Constrast coefficient Group Group Group S-stat Meaning X1 X2 X3 (1 - 1)Fa,1-1,0-1 Reject HO or not?
