In testing for differences between the median of two independent populations,the null hypothesis is
A)H 0 : M D =0.
B)H 0 : M D = 0 .
C)H 0 : M 1 -M 2 =0.
D)H 0 : M 1 - M 2 $\neq$ 0 .

Question

Quizplus · Accepted Answer

Choice C represents the correct null hypothesis for testing the difference between medians of two independent populations. It involves the difference between the population medians being equal to zero, as represented by S1S1P0 term. The alternative hypothesis would be that the population medians are not equal. The other answer choices do not accurately represent the correct null hypothesis for this scenario.
