In testing for differences between the means of two paired populations, an appropriate null hypothesis would be: A) H0 : μD = 2 B) H0 : μD = 0 C) H0 : μD 0

Question

In testing for differences between the means of two paired populations, an appropriate null hypothesis would be:
A) H0 : μD = 2
B) H0 : μD = 0
C) H0 : μD < 0
D) H0 : μD > 0

Quizplus · Accepted Answer

The appropriate null hypothesis for testing differences between the means of two paired populations is that there is no difference, which is represented by H0: μD = 0. This means we assume the mean difference (μD) between the paired samples is zero until evidence suggests otherwise.
