Consider a hypothesis test of difference of means for two independent populations $x_{1}$ and $x_{2}$ (a) What does the null hypothesis say about the relationship between the two population means? (b) If the sample test statistic has a $z$ distribution, give the formula for $z$ (c) If the sample test statistic has a $t$ distribution, give the formula for $t$.
Hypothesis Testing
