Ask the Professor Forum

Good Afternoon Mr. McGuckian,

I have a question, in the tests to compare population means, how do I know when should I use the critical value method or the P-value method?... Will it always be stated in the problem? or there are other cues that would indicate me to use either one of the two?

Thank You Very Much

Adriana Nava

Hi Adriana,

It will be stated in the problem. If the problem is multiple choice, you can simply see what is being used in the answer choices.
