Question

In testing for differences between the means of two related populations, the null hypothesis is
A) H0 : µD < 0.
B) H0 : µD > 0.
C) H0 : µD = 0.
D) H0 : µD = 2.

Quizplus · Accepted Answer

For testing the difference between the means of two related populations, the null hypothesis states that the mean difference (µD) between the two populations is equal to zero. Therefore, the correct null hypothesis is H0 : µD = 0. The other options are incorrect as they suggest a direction or a specific value for the mean difference.
