The Survey of Study Habits and Attitudes (SSHA) is a psychological test that measures the motivation, attitudes, and study habits of college students. Scores range from 0 to 200 and follow (approximately) a Normal distribution, with mean of 110 and standard deviation s = 20. You suspect that incoming freshman have a mean m, which is different from 110 because they are often excited yet anxious about entering college. To verify your suspicion, you test the hypotheses

H0: m = 110, Ha: m 110

You give the SSHA to 50 students who are incoming freshman and find their mean score.

The P-value of the test of the null hypothesis is

A)the probability, assuming the null hypothesis is true, that the test statistic will take a value at least as extreme as that actually observed.
B)the probability, assuming the null hypothesis is false, that the test statistic will take a value at least as extreme as that actually observed.
C)the probability the null hypothesis is true.
D)the probability the null hypothesis is false.
