Question

Consider a population with a population proportion p and a sample from the population with sample proportion p-hat. Which of the following describes the purpose of the one-sample z-test?

A. To estimate the value of p-hat

B. To estimate the value of p

C. To estimate a margin of error for p-hat

D. To estimate the probability of observing a value as extreme as p-hat given p

E. To estimate the probability of observing a value as extreme as p given p-hat

Answer 1

D. To estimate the probability of observing a value as extreme as p-hat given p

Step-by-step explanation:

This is the purpose of hypothesis testing in general. The question is always: given the population parameter, what are the chances of observing the sample statistic?
