1. The amount of time it takes a patient to fully recover from a virus-inflicted illness (in days) follows a normal distribution with unknown mean i and a variance equal to 9m?. Find the most powerful test to verify the null hypothesis that i = k against the alternative that = 2k on the base of k independent observations, for a significance level of n%. Calculate the power of this test (for the alternative hypothesis). What is...

3. (4 points) Let X equal the number of pounds of butterfat produced by a Holstein cow during the 305-day milking period following the birth of a calf. Assume that the distribution of X is N(μ, σ2-1402). To test the null hypothesis Ho : μ-175 against the alternative hypothesis Ha : u 715, let the crtical region be defined by 668.94, where x is the sample mean of n 25 butterfat weights from 25 cows selected at random (a). What...
