A wildlife biologist is studying the prevalence of rabies in skunk populations in two different counties, with the following results:
She wants to test the hypothesis that the proportions in the two counties differ, and sets her Type I error to ? = 0.05. If our biologist is going to use the two-sample z test, what does she use for a critical value?
(a) ±1.645 (b) ±1.96 (c) +1.645 (d) ±2.81 (e) ?1.96
Homework Answers
This is a two tailed test
So , critical values = + Z0.05/2 = + 1.96
Option-B) ±1.96
