In the first box, write the type of distributions W follows

In the second box, write the expectation of W

In the third box, write the variance of W

We have normal variables X and Y: X~N(7, 1); Y~N(2, 3); Cov(X, Y)=0 and suppose we have another variable W = 2X + Y In the first box, write the type of distributions W follows In the second box, write the expectation of W In the third box, write the variance of W
