..., Xn be iid observations from a location-scale family. Let Ti(X1,..., Xn) Let X1,...,) and T2(X1,...,Xn) be two statistics that both satisfy T:(arı + b,..., ar, + b) = aT;(x1,..., In) for all values of r1,..., In and b and for any a > 0. (a) Show that T1/T2 is an ancillary statistic. (b) Let R be the sample range and S be the sample standard deviation. Verify that R and S satisfy the above condition so that R/S is an ancillary statistic.
