If the linear correlation between two variables is negative, what can be said about the slope of the regression line?
Added by Sara S.
Step 1
Step 1: The formula for the slope of the regression line (B) is B = (nΣXY - ΣXΣY) / (nΣX^2 - (ΣX)^2), where n is the number of data points, Σ represents the sum of the values, X and Y are the variables, and XY is the product of X and Y. Show more…
