If we are interested in testing whether the mean of population 1 is significantly larger than the mean of population 2, the correct null hypothesis is A) H0: μ1- μ2 ≥ 0 B) H0: μ1- μ2 = 0 C) H0: μ1- μ2 0 D) H0: μ1- μ2

Question

If we are interested in testing whether the mean of population 1 is significantly larger than the mean of population 2, the correct null hypothesis is
A) H0: μ1- μ2 ≥ 0
B) H0: μ1- μ2 = 0
C) H0: μ1- μ2 > 0
D) H0: μ1- μ2 < 0

Quizplus · Accepted Answer

The correct null hypothesis for testing whether the mean of population 1 is significantly larger than the mean of population 2 is H0: μ1- μ2 = 0. This is because the null hypothesis always assumes that there is no difference between the two population means unless there is evidence to the contrary. In this case, the alternative hypothesis would be Ha: μ1- μ2 > 0, which states that the mean of population 1 is greater than the mean of population 2.
