 Question 564064: Determine the critical region and critical values for z that would be used to test the null hypothesis at the given level of significance, as described in each of the following: A)hou = 71 hau= 71 = null = 0.05 B)hou greater than27 and hau less than 27 null = 0.10 C)hou less than 60 and hau greater than 60 null = 0.01Answer by stanbon(57387)   (Show Source): You can put this solution on YOUR website!Determine the critical region and critical values for z that would be used to test the null hypothesis at the given level of significance, as described in each of the following: A)hou = 71 hau= 71 = null = 0.05 Ho: u = 71 Ha: u # 71 alpha = 0.05 Critical region: z<-1.96 or z>+1.96 --------------------------------------------- B)hou greater than27 and hau less than 27 null = 0.10 Ho: u >= 27 Ha: u < 27 alpha = 10% ---- Critical region: z < -1.2816 ---------------------------------------------- C)hou less than 60 and hau greater than 60 null = 0.01 Ho: u <= 60 Ha: u > 60 alpha = 1% Critical region: z > 2.3263 ================================ Cheers, Stan H. =================
