Step 1
The problem asks us to show that the sample mean \( \bar{X} \) is not invariant to rescaling. This means that if we scale each data point in a dataset by a constant factor \( a \), the sample mean of the new dataset will not be the same as the original sample Show more…

(a) Let (X, p) be a metric space. Define p(x,y) = (1 + p(x,y)). Then prove that (X,d) is a metric space. (b) Let P and P2 be metrics on the same set X. Show that there exists a metric on X such that p(x,y) P1(x,y) for i = 1,2 and for all x,y X.
