If we assume the null hypothesis is true in a nondirectional test,then ì₁ and ì₂ will be equal,so ì₁ - ì₂ will equal 0.

When assuming the null hypothesis is true in a nondirectional test, we expect the population means (ì) of two groups (S1U1B11 and S1U1B12) to be equal. Therefore, the difference between the two population means (ìS1U1B11 - ìS1U1B12) will be zero.
