In testing a hypothesis about a population proportion p, the z-test statistic measures how close the computed sample proportion has come to the hypothesized population parameter.

Question

In testing a hypothesis about a population proportion p, the z-test statistic measures how close the computed sample proportion  has come to the hypothesized population parameter.

Quizplus · Accepted Answer

The z-test statistic compares the difference between the sample proportion and the hypothesized population proportion in terms of standard errors. It measures how many standard deviations the sample proportion is away from the hypothesized proportion, indicating how likely it is that the difference is due to chance or sampling error. Therefore, it does measure how close the computed sample proportion has come to the hypothesized population parameter.
