# Question

Solve the double inequality –tα/2,n–2 < t < tα/2,n–2 with t given by the formula of Exercise 14.25 so that the middle term is y0 and the two limits can be calculated without knowledge of y0. Although the resulting double inequality may be interpreted like a confidence interval, it is not designed to estimate a parameter; instead, it provides limits of prediction for a future observation of Y that corresponds to the (given or observed) value x0.
