Question

Chapter 10 presented methods for comparing means for two groups. Explain how it’s possible to perform a significance test of equality of two population means as a special case of a regression analysis. (Hint: The regression model then has a single explanatory variable—an indicator variable for the two groups being compared. What does μ1 = μ2 correspond to in terms of a value of a parameter in this model?)
