4. Suppose U has a uniform (0, 1) distribution. Then, we could write the p.d.f. as either for 0

4. Suppose U has a uniform (0, l) distribution. Then, we could write the p.d.f. as either fU(t) = 0, otherwise or fU(t) Suppose Y = (b a)U+a where a < b. Use the scaling rule to find the p.d.f. of Y, which I suggest you denote by fy so that we do not confuse it with the pdf fU
