Suppose that X is a Bernoulli random variable with P(X= 1) = p and P(X= 0) = 1 - p. a. What are the expectation and variance of X? b. What is the distribution of X2? c. What is the distribution of Y = ax + b?, where a 0 and b are constants d. In part (c), find a and b such that Y takes on values -1 and 1? e. What are the expectation and variance of Y obtained in part (d)? Suppose that X is a Bernoulli random variable with P(X= 1) = p and P(X= 0) = 1 - p. a. What are the expectation and variance of X? b.
