must not be rejected at the 0.01 level

d. must not be rejected at any other level

Explanation:
Detailed explanation-1: -So if you reject at =0.025, you may or may not reject at =0.01. But if you reject at =0.01, you’ll always reject at =0.025. Am I correct in my reasoning? Short answer: yes.
Detailed explanation-2: -Most authors refer to statistically significant as P < 0.05 and statistically highly significant as P < 0.001 (less than one in a thousand chance of being wrong).
Detailed explanation-3: -Answer and Explanation: The answer is “FALSE.” To not reject the null hypothesis at the significance level of 0.10, the p-value has to be above 0.10 . If the p-value is above 0.10, it is also above 0.05; the null hypothesis is not rejected at 0.05 significance either.
