17.a. In a repeated measures study if a person provides one score, and then drops out of the study, we can still use that score to get our overall mean difference, we just can't use it to calculate the variance of the difference scores.

True

False

b. A sample has a mean of M = 42 and a standard deviation of s = 3.3, and produces a t statistic of t = 2.04.For a two-tailed hypothesis test that hasa critical cutoff Tof 1.96, do you reject the null or not?

a.there is no way to tell if you can reject or not

b.reject the null hypothesis

c.none of the answers are correct

d.cannotreject the null hypothesis
