Answer 2

Answer:

The correlation coefficient is a measure of the linear relationship between the two variables.

If r=0, this implies that there is no linear relationship between the two variables but there may be some other non-linear relationship.

X and Y are independent, normally distributed random variables with mean 0 and variance 1.
