A8 Let a > 0 be the critical value of a two-sided z-test, b>0 the critical value of a two-sidedt test, and c> 0 the critical value of a one-sided t-test. All these tests use the samesignificance level a. Consider the following statements:(i) a > c(ii) a c(iv) a = cWhich of these statements must be true?A: (i), (ii), and (iv) B: (i) and (iii) C: (i) and (iv)E: (ii) onlyD: (ii) and (iii)

(i) True: Since the two-sided t-test is less powerful than the one-sided t-test, the critical value…

State your conclusion to the hypothesis test. Sally was interested in whether the number of m&m's was uniform over all 6 colors (the same number of m&m's for each color). The table categorizes the number of m&m's of each color found in a 1-pound bag. Color Brown Red Yellow Blue Orange Green Number 70 85 81 79 93 96 Perform a Chi-square goodness-of-fit test at the 5% significance level and state your conclusion. Hint: the test-statistics is χ2=5.43 A.) There is not sufficient sample evidence to suggest that the distribution of colors is not uniform. B.)
