H₁:p ≠ 0.78

Level of Significance α = 0.15

-1.28 and 1.28

-1.44 and 1.44

-0.15 and 0.15

-1.34 and 1.34

Solutions

Expert Solution

H0: p=0.78

H1: p≠0.78

Given test is one sample proportion z-test. This test is two tailed.

Level of significance (alpha) = 0.15

Therefore, the critical value is,

-1.44 and 1.44

## answer : 2nd option is correct.
