Quizplus · Accepted Answer

The z test statistic measures the number of standard deviations between the sample proportion and the hypothesized population parameter, which allows us to determine the probability of obtaining such a result by chance alone. Therefore, it measures how close the computed sample proportion has come to the hypothesized population parameter.
