Question

Suppose that a population is known to have a mean of 80.If a researcher predicts the experimental treatment will produce an increase in the population mean,then the null hypothesis for this statistical hypothesis test would state
A)µ > 80
B)µ $\ge$ 80
C)µ $\le$  80
D)µ < 80

Quizplus · Accepted Answer

The null hypothesis typically states that there is no effect or no difference. In this case, since the researcher predicts an increase, the null hypothesis would state that the mean is less than or equal to 80 (µ ≤ 80), indicating no increase or a decrease compared to the predicted outcome.
