Lversus the that e -1versus the 5. In the N(O, 2) family, show fully how to test the null hypothesis that alternative hypothesis that 5, at the 0.05 signifance level, but with the greatest possible power, for a sample of size 16. Be as fully explicit as possible, including justifying that your test is indeed most powerful at this significance level. You can use Ф-0.05)--1.645. Be sure to actually compute the power, as well !...
