Exercise 4 Let X~ N(ux, o) and Y ~ N(μy, o). Suppose we are given the following indepen- ently sampled data for X and Y³: sample for X Sample for Y 24.8 12.8 11.1 11.1 15.9 12.2 18.3 8.9 5.6 12.8 17.3 11.3 26.6 26.3 25.2 23.3 22 20.2 26.1 21.1 14.6 14.5 21.8 22.8 11.5 21.5 22.3 31 ompute a 95% confidence interval of x-μy (i) using the knowledge that o = o = 4.7; (ii) assuming we do not know the values of ox, oy, but we still know that ox = oy = 0 for some unknown σ.
