It is assumed that null hypothesis for difference between po

It is assumed that null hypothesis for difference between population- means is rejected if mu_1 - mu_2 does not contain zero. What is the significance of this assumption?

Solution

here

H0; mu1=mu2 vs H1: not H0

so, here we assume that the tuo sample comes from same distibution under H0 but if we get the sample that doest support our assumption then m1-m2 not equal to zero we have to accept
