suppose that the random variable X representing the probability that a random college student voted in the last student body election has the density function f(x) = kx^2(1-x)I(0,12)(x). A) show that a unique value of k for which f(x) is a legitim
Suppose that X is a continuous random variable with density function given by f(x) = (3/4)(1-x^2)I(-1,1)(x). Obtain the cdf of X, and calculate its mean and variance.
(Hint: (sigma) iP(X > i) = sigma i(sigma P(X = k)) Now interchange the order of summation and proceed.) sigma) is supposed to be sigma, from i=1 to infinity. > is greater than or equal to
