Determine the critical value and critical region that would be

Determine the critical value and critical region that would be used in the classical approach to test the null hypothesis for each of the following multinomial experiments.,a. Ho: P(1) = P(2) = P(3) = P(4) = 0.25, with a = 0.05 ,b. Ho: P(I) = 0.25, P(II) = 0.40, P(III) = 0.35 with Explain how 9_3_3_1 becomes 9/16,3/16,3/16 and 1/16 in Example ,In Example ,Reorganize the alternative hypothesis so that the critical region will be the right-hand tail:
