Question

Exercise 4. Let X1, . . . , Xn, Xn+1 be a sample from a normal population having an unknown mean μ and variance 1. Let Xn = 1/n ∑i=1 to n Xi be the average of the first n of them. i) What is the distribution of Xn+1 − Xn? (ii) If Xn = 4, give an interval that, with 95% confidence, will contain the value of Xn+1.
