In comparing the difference of the means between two groups,the null hypothesis can also be stated as:
A) $ \mu_{1}-\mu_{2}=0 $
B) $ \mu_{1}+\mu_{2}=0 $
C) $ \mu_{1} \mathrm{x} \mu_{2}=0 $
D) $ \mu_{1} / \mu_{2}=0 $

The null hypothesis for comparing the difference of the means between two groups is that there is no significant difference between the means, which can be expressed as the mathematical statement $ \mu_{1}-\mu_{2}=0 $.

In Comparing the Difference of the Means Between Two Groups,the μ1−μ2=0 \mu_{1}-\mu_{2}=0 μ1​−μ2​=0
