The mean annual tuition and fees for a sample of 12 private colleges was with a standard deviation of . You wish to test whether the mean tuition and fees for the population of all private colleges is greater than . Calculate the test statistic value and give its P-value for this test. Assume the population is normally distributed.

A) t = 2.38; 0.01 < P-value < 0.02

B) t = 2.38; 0.02 < P-value < 0.05

C) z = 2.38; P-value = 0.0087

D) t = 2.38; 0.01 < P-value < 0.025

E) z = 2.38; P-value = 0.0174
