Answer 2

Answer:

The Corr(ax,by) bear sign according to two signs.

Step-by-step explanation:

Given: Corr(ax,by), where a and b have same algebraic sign.

To determine sign of Corr(ax,by).

The '+' or '-' sign is given to the correlation coefficient based on the signs of the two regression coefficients.

We know that; r = $\pm=\sqrt{({b_{xy} }*b_{yx} )}$

where r is the correlation coefficient and $b_{xy} , b_{yx}$   are the regression coefficients.

Disclaimer: The question is incomplete.

The complete question is:

When two regression coefficients bear same algebraic signs, then correlation coefficient is:

Positive

Negative

According to two signs.

Zero
