C)+0.5
D)1.00

Question

Quizplus · Accepted Answer

In a one-tailed test, if the test statistic z is zero, it means the sample mean is exactly equal to the population mean under the null hypothesis. The p-value is the probability of observing a test statistic as extreme as, or more extreme than, the observed value. For a lower bounds test, this corresponds to a p-value of 0.5.
