    I don’t know if I made a mistake somewhere along in the calculation but i’m having a problem… I used to full figures in thousands for costs and hundreds for units. So, for I have Sum(X) = 2800, Sum(Y) = 420,000, Sum(XY) = 187,000,000, Sum(X^2) = 1,400,000 and Sum(Y^2) = 26,550,000. When I plugged these values into the equation, (the numerator): Square root of [(7*1,400,000)-(2800^2)] X [(7*26,550,000)-(420,000^2)]. My problem is with the values in the last bracket. 420,000^2 is more than (7×26,550,000) which means under the square root I’m getting a negative value. Please Help
