32-a5 refer 10 15 20 25 30 10 15 20 25 30 Value Value The figure value values. The mean value in the left panel is 20, the mean values in the right panel are 18, 20, and 22. The above imustrates the distribution of response values in the population under two scenarios. f true fleft panel), then values sampled from each group actually come from the same population of ·" HA is true, values from each group come from separate populations that have different mean variance of each distribution is 12.25. Remember that standard errors and variances are on different scales 32) In terms of probability, event A (HO is true) and event B (HO is false) are d) e) a and b a, b, and c b) Mutually exclusive c) Complementary 33) The figure illustrates the theory behind what statistical test? a) One-way ANOVA b) Two-sample t test c) Two-way ANOVA d) Chi-squared test e) Tukey-Kramer test 34) A researcher takes samples of 10 individuals from each group. If the groups actually come fromth same population (HO is true), then we expect the observed variance among sample means to be b) 1.225 0 d) 7.365 e) 12.250
