Question

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) and , a = 0.05 (B) and , a = 0.01 (C) and , a = 0.10

Explanation / Answer

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. Ho: µ = 25 and Ha: µ ? 25, a = 0.10 Critical Values: z = +/-1.645 Critical Region: z < -1.645 or z > +1.645 -------------------------------------------------- b. Ho: µ = 32 and Ha: µ >32, a = 0.01 Critical Value: z = 2.326 Critical Region: z >= 2.326 --------------------------------------------------- c. H0: µ =13 and Ha: µ < 13, a = 0.05 Critical Value: z = -1.645 Critical Region: z < -1.645 =================================== Cheers, Stan H.
