Question

You wish to test the following claim ( H 1 ) at a significance level of α = 0.02 . H o : p = 0.64 H 1 : p ≠ 0.64 You obtain a sample of size n = 519 in which there are 349 successful observations. What is the critical value for this test? (Report answer accurate to two decimal places.) critical value = ±

Answer 1

Given that, $\alpha = 0.02$

And test is two tailed test.

Critical value for test is $Z_{\alpha/2} = Z_{0.01} =$

± 2.33

Using Normal probability table.
