What is the critical Z value for the following scenario:
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
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.
