You are going to test the claim that more than 60% of men refuse to ask for directions when they get lost. If you use a significance level of 0.10, what will the critical number be for your rejection region?

Solution

At a significance level of 0.10 and for a one-tailed test, the critical number (Z score) is 1.282. (A two-tailed test for \"not equal to 60%\" would have a critical number of 1.645.)
