A) Reject null hypothesis because the test value 15 is less than the critical value 17.
B) Reject null hypothesis because the test value 15 is greater than the critical value 14
C) Do not reject null hypothesis because the test value 15 is less than the critical value 17
D) Do not reject null hypothesis because the test value 15 is greater than the critical value 14
