2. Determine the critical z value that would be used to test a hypothesis under the conditions given in each of the following: (5 points each) 1) Ho: M=150, H1: H=150; a= 0.05 2) Ho: H 220, H1: H25; a= 0.05 4) For 2.1) Ho: M=150, H1: #150; a= 0.05, if the calculated z = -1.59, should you reject Ho or fail to reject Ho according to the corresponding z critical value? 5) For 2.2) Ho: H >20, H1: H 25; a= 0.05, if the calculated z = 2.21, should you reject Ho or fail to reject Ho according to the corresponding z critical value
