For right sided test for proportion, use z-table to find the critical value when alpha = .08
Please explain how to find
SOLUTION:
From given data,
For right sided test for proportion, use z-table to find the critical value when alpha = .08
Significance level = = 0.08
Critical value for right tailed test would be 1.405
As the test is right sided, critical region lies to the right of
the curve
P(z > Z) = 0.08
Z = 1.405
Explanation:
P(z > 1.405) = 1 - P(z < 1.405)
P(z > 1.405) = 1 - 0.9192
P(z > 1.405) = 0.0808
That is,
If the critical value z = 1.405 we get = 0.08 so the answer is
critical value = z = 1.405
Below is the table where we first located the area i.e. 0.08 and then respective z-value is captured.
