The critical value defines the boundary beyond which one can reject the null hypothesis.It is given that the test is left tailed and . Using Excel, the critical value is computed. The function used is =NORM.S.INV(0.005) and the output value is -2.58. Tthe snip is attached below:It is given that the test is right tailed and . Using Excel, the critical value is computed. The function used is =NORM.S.INV(1-0.0005) and the output value is 3.29. The snip is attached below:It is given that the test is two-tailed and . Using Excel, the critical values are computed. The functions used are =NORM.S.INV(0.001/2) and =NORM.S.INV(1-0.001/2). The output values are -3.29, 3.29. The snips are attached below:It is given that the test is two-tailed and . Using Excel, the critical values are computed. The functions used are =NORM.S.INV(0.01/2) and =NORM.S.INV(1-0.01/2). The output values are 2.58, -2.58. The snips are attached below:The critical value is -2.58.The critical value is 3.29.The critical values are -3.29, 3.29.The critical values are 2.58, -2.58.
