When conducting a hypothesis test concerning the population proportion, the value of the test statistic is calculated as ________. A) z = B) t_df = C) z = D) t_df =

Question

Quizplus · Accepted Answer

The test statistic for a hypothesis test concerning the population proportion is given by z = (p̂ - P) / sqrt(P(1-P)/n), where P is the hypothesized proportion, p̂ is the sample proportion, and n is the sample size. Therefore, the correct choice is C. Choice A and B are incorrect because they do not correctly represent the formula for the test statistic for a population proportion. Choice D is incorrect because it uses a t-test instead of a z-test for the population proportion.
