Explain with reason whether the following statements are true, false, or uncertain:
a. Since the correlation between two variables, Y and X, can range from −1 to +1, this also means that cov (Y, X) also lies between these limits.
b. If the correlation between two variables is zero, it means that there is no relationship between the two variables whatsoever.
c. If you regress Y_i on Ŷ_i (i.e., actual Y on estimated Y), the intercept and slope values will be 0 and 1, respectively.
