A random sample of n observations is selected from a normal population to test the null hypothesis that =10. Specify the rejection region for each of the following combinations of Ha, , and n. a. Ha:10; =0.01; n=13 b. Ha: >10; =0.05; n=25 c.Ha: >10; =0.10; n=8 d.Ha: <10; =0.05; n=11 e.Ha: 10; =0.10; n=17 f. Ha: <10; =0.01; n= 5
