Quizplus · Accepted Answer

A directional alternative hypothesis has a greater than or less than sign in it, indicating the direction of the expected difference between the sample mean and the hypothesized population mean. Option B has a greater than sign indicating that the sample mean is expected to be greater than the hypothesized population mean. Option A and C have equal signs indicating that the sample mean is expected to be equal to the hypothesized population mean, making them non-directional hypotheses. Option D has a numeric value in the hypothesis, making it non-directional as well.
