7. The covariance between X and Y is calculated and recorded as sxY (and sxy is a positive number). A linear transformation is performed on X. The linearly transformed variable is called W, where W; = (4)X;. The covariance between W and Y is calculated and recorded as sWY. Which statement is correct? In this example, sxY would be less than swy. In this example, sxy would be equal to swy. In this example, sxy Would be greater than swy. A) B)
