Use a type of remembering called "memotechnia." Like me. I had some trouble with remembering some stuff for a Science test I have on Monday, (I'm in the 5th grade), and I used a phrase, "King Philip Came Over For Good Soup", to remember all of the 7 groupings of the domain Eukarya. Next thing I know, I ask myself the questions, and I know it all! You should try memotechnia. It really works! :)

P.S- If you don't think you can practice memotechnia by yourself, have a freind help. Tell them I told you! Don't take the memotechnia credit for yourself.

Any decision based on the test statistic is marginal in such a case. It is important to remember that the test statistic is derived on the basis of the null hypothesis and does not make use of the distribution under the alternative hypothesis.
