Suppose f(x) = c/x4, x>4, is the p.d.f. of the random variable X. Find a) The value of the constant c, b) P(x<5), c) The standard deviation of X, and d) The 70th percentile of X. Suppose f(x)=(2/3)x, 1≤x≤2, is the p.d.f. of the random variable X, and Y = X³. Find a) the standard deviation of Y, and b) the median of X. Suppose f(x)=16xe 4x, x>0, is the p.d.f. of the random variable X. Find the c.d.f. of X. Note: this involves using integration by parts. Suppose. F(x) = (1/162)(x-1)2 (4x+7), 1≤x≤ 5 is the c.d.f of the random variable X, find a) The p.d.f. of X, b) P(x > 4), and c) P(2≤ x ≤3).. Suppose X is a continuous uniform random variable with = 5 and o = 20/√3. Find a) the p.d.f of X, b) the c.d.f. of X.
