The covariance between X and Y is calculated and recorded as sXY (and is a non-zero number). A linear transformation is performed on X. The linearly transformed variable is called W, where Wi = aXi , and a is less than -2. A linear transformation is also performed on Y . The linearly transformed variable is called Z, where Zi = Yi/a. The covariance between W and Z is calculated and recorded as sW Z. In this example...
(a) sXY would definitely be the same as sW Z
(b) sXY would definitely not be the same as sW Z
c) sXY might be the same as sW Z, but might not be
