Question

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

Quizplus · Accepted Answer

The null hypothesis in testing for differences between the means of two related populations is typically that the mean difference between the two populations is zero. Therefore, the correct statement for the null hypothesis is H₀: μD = 0. Choices A, C, and D all incorrectly specify a non-zero value for the mean difference.
