A student applying to your graduate program in psychology has a GRE score that is 2.5 standard deviations above the mean. Suppose that the beta in a particular situation for predicting graduate school GPA from GRE scores is .6. What will be this person's predicted Z score for graduate school GPA?
A).25
B)1.5
C)2.5
D)2.7

To find the predicted Z score for graduate school GPA, we need to use the formula Z predicted = beta(GRE Z score).

Given that the student's GRE score is 2.5 standard deviations above the mean, we can calculate their GRE Z score as follows:

GRE Z score = (X - mean)/SD = (2.5*SD - 0)/SD = 2.5

Substituting this value into the formula:

Z predicted = 0.6 * 2.5 = 1.5

Therefore, the predicted Z score for graduate school GPA is 1.5, which corresponds to choice B.
