Question: When we standardize the values of a variable, the distribution of standardized values has mean 0 and standard deviation 1. Suppose we measure two variables X and Y on each of several subjects. We standardize both variables and then compute the least-squares regression line. Suppose the slope of the least-squares regression line is -0.44. We may conclude that

(a) the intercept will also be -0.44.

(b) the intercept will be 1.0.

(c) the correlation will be 1/-0.44.

(d) the correlation will be 1.0.

(e) the correlation will also be -0.44.
