Suppose a principal claims that the mean test score at her school is greater than the national average. She performs a hypothesis test and finds the test statistic to be t = 1.77 and she knows the critical value for this test to be t = 1.98. What can she conclude? A. There is not sufficient evidence to support her claim since the test statistic falls in the critical region. B. There is not sufficient evidence to support her claim since the test statistic does not fall in the critical region. C. There is sufficient evidence to support her claim since the test statistic does not fall in the critical region. D. There is sufficient evidence to support her claim since the test statistic falls in the critical region
