Answer #1

Answer:

1.

Given,

significance level = 0.10

alpha/2 = 0.1/2 = 0.05

Here it is two tailed test, so the critical value is +/- z(alpha/2) = +/- 1.645

Rejection region :

Reject Ho, if z > 1.645 or z < - 1.645

Option D

2.

alpha value is not given

Please post the remaining questions as separate post. Thank you.
