Consider random numbers X generated uniformly on the interval (-1,9). What is the expected value E(X)? Hint: find the expectation of g(x) = x with an appropriate PDF for uniform distribution in the given interval. What is the expected value E(X)? Give your answer correct to two decimal places. Hint: try to use g(x) = x with an appropriate PDF for uniform distribution in the given interval. What is the variance of X? Give your answer correct to two decimal places.
