Question: Let Y = X1 + X2 + + X15 be the sum of a random sample of size 15 from the distribution

Let Y = X1 + X2 + · · · + X15 be the sum of a random sample of size 15 from the whose pdf is f(x) = (3/2)X2, −1 < x < 1. Using the pdf of Y, we find that P(−0.3 ≤ Y ≤ 1.5) = 0.22788. Use the central limit theorem to approximate this probability
