For right sided test for proportion, use z-table to find the critical value when alpha = .08

Please explain how to find

Expert Solution

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.

When do we use in probability: -the area to the right of Z (when to use right Z-table) -the area to the left (when to use left Z-table)

When do we use in probability: -the area to the right of Z (when to use right Z-table) -the area to the left (when to use left Z-table) -and when do you subtract 1 from the area to the left instead of using the right table ?
