Question

1. The pdf of Y is f(y) = k(y^3) I[2,3](y) where k is a constant, real number.

(a) (5 points) Calculate the value of k so that f(y) is a valid pdf.

(b) (5 points) Find E(Y ). Hint: write k as a fraction so you don’t have to round until the end.

(c) (5 points) Find the 50th percentile of Y .

(d) (2 points) Briefly (1-2 sentences) explain why your answers to parts (b) and (c) make sense.
