C)​p < 0.01.
D)p < 0.001.

Quizplus · Accepted Answer

A one-tailed t-test with 14 degrees of freedom at the 0.05 level would have a critical value of 1.761. Since the calculated t-value of 2.25 is larger than the critical value, we reject the null hypothesis and conclude that the results are statistically significant. The p-value associated with this t-value would be less than 0.05, but since this is a one-tailed test, we only consider the area in one tail, which is 0.025. Therefore, the correct answer is A.
