34. Consider the following 3 boxplots, representing 3 separate and independent samples of size 20. 20 18 16 14 12 10 A A B C Consider the following 4 statements: I. If we performed a one-way ANOVA on these 3 samples, the p-value would be small. II. If we carried out a t-test of Ho: A = up against a two-sided alternative, the p-value would be small. III. The use of the pooled-variance t procedures for the test of Ho: A = Ac would be a bad idea, as the assumptions are clearly violated. IV. The standard deviation of Sample C is greater than the mean of Sample C. How many of these statements are true? (a) 0 x (b) 1 (c) 2 (d) 3 (0) 4
