Question:
Exercise 6.8.5 Consider the model yi = β0 +β1xi +ei, eis i.i.d. N(0,σ 2), i =
1,2,3, . . . ,n. If the xis are restricted to be in the closed interval [−10,15], determine how to choose the xis to minimize
(a) Var(ˆβ0).
(b) Var(ˆβ1).
(c) How would the choice of the xis change if they were restricted to the closed interval [−10,10]?
