Q4. (30') (Properties of Expectation and Variance) (a) (15') Given an original set of data, we multiply each number in the set by 2 and then subtract 3 to obtain a new set of data. If the expectation of the new set of data is 7 and the variance is 4, calculate the expectation and variance of the original set of data (b) (15') Suppose the r.v. X follows Poisson distribution and P(X-1) - P(X-2). Calculate the expectation and variance of X
