Question

Assume that a = 0.05. Find the rejection region for both test statistics Y- and Ý for testing oln = 0 versus Hq :> 0 with n = 35 and 0 = = 10. Ho : 1 =

Answer 1

Solution :

This is the right tailed test,  

The null and alternative hypothesis is ,

H₀ :   $\mu$ = 0

H_a : $\mu$ > 0

$\alpha$ = 0.05  

P(Z > z) = 0.05

= 1 - P(Z < z) = 0.05  

= P(Z < z) = 1 - 0.05

= P(Z < 1.65 ) = 0.95  

Rejection region = z > 1.65
