Determine the critical z value that would be used to test a hypothesis under the conditions given in each of the following: 1) For 2.1) H0: µ=150, H1: µ≠150; α= 0.05, if the calculated z = -1.49, should you reject H0 or fail to reject H0 according to the corresponding z critical value? 2) For 2.2) H0: µ ≥20, H1: µ<20; α= 0.05, if the calculated z = -1.69, should you reject H0 or fail to reject H0 according to the corresponding z critical value? 3) For 2.3) H0: µ ≤ 25, H1: µ>25; α= 0.01, if the calculated z = 2.11, should you reject H0 or fail to reject H0 according to the corresponding z critical value?
