Question:

Let D1, D2, . . . , Db be the within-block differences as defined in this section. Assume that the Di 's are normal with mean μD and variance σ2D , for i = 1, 2, . . . , b. Derive a formula for a 100(1 − α)% confidence interval for μD. Apply this formula to the data of Case Study 13.3.1 and construct a 95% confidence interval for the true average hemoglobin difference ("before walk" − "after walk").
