Question

Applying Statistical Inference: An Example When we set our significance level at .01, this corresponds to the notation,
A)p < .01.
B)p = .01.
C)p ≥ .01.
D)p > .01.

Quizplus · Accepted Answer

Setting the significance level at .01 means that we are willing to accept a maximum probability (p-value) of .01 for rejecting the null hypothesis. Therefore, if the p-value is less than .01, we can reject the null hypothesis at this level of significance. Thus, the correct notation is p < .01.
