A) the standard deviation of the "distribution of differences between means" is figured B) a comparison is made against a Z distribution C) the variance of the "distribution of differences between means is figured D) the pooled estimate of the population variance is figured 8-If a study measures two groups on each of 100 variables, and the experimenter carries out at test for independent means for each variable (that is, 100 t tests) using the 01 significance level, how many of those tests would be expected to give statistically significant results? A) 1 B) 10 C) 0 D) 100 13- For two sample t test, the mean of the distribution of differences between means" when the null hypothesis is true is greater than 1. A) True B) False
