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…

A hypothesis test is conducted in order to determine the average weight of a Kit Kat bar.using the following null and alternative hypotheses: H0: The average weight of a Kit Kat bar is 1.5 ounces. HA: The average weight of a Kit Kat bar is greater than 1.5 ounces. Using complete sentences, explain what both a Type 1 and Type 2 error would be in context of this hypothesis test.
