QUESTION: If we reject the null hypothesis, can we claim to have proved that the null hypothesis is false? Why or why not?

Choose the correct answer below.

A. Not necessarily, if the test conditions are satisfied and the p-value is appropriately small, the null hypothesis can only be proven false if the power is appropriately large.

B. No, if the p-value is sufficiently small, the null hypothesis is unlikely to be true, but unlikely is not the same as impossible.

C. Yes, if the test conditions are satisfied and the p-value is smaller than the significance level, then the null hypothesis is proven to be false.

D. Not necessarily, if the test conditions are satisfied and the p-value is appropriately small, the null hypothesis can only be proven false if the significance level is appropriately small.
