Suppose a researcher conducts a t test for dependent means in which it is predicted that there will be a decrease in unemployment from before to after a particular job-skills training program. The cutoff t needed is -1.833. The standard deviation of the distribution of means of change scores is 2.0 and the mean change score for the sample studied is an increase of 5.2. What is the t score?
A. 5.2/-1.833=-2.84
B. 2/5.2=.38
C. 5.2/2=2.60
D. 22
