Suppose the following two estimated regression equations are obtained from data on monthly demand of a product (y) and its monthly price (x), over 20 months, in appropriate units: (a) x+ 6y =4 and (b) 3x+ 4y= 8. One of the regression equations are obtained by regressing y on x and the other by regressing x on y. Then calculate:

(i) The correlation coefficient between monthly demand and monthly price.

(ii) The estimated regression line slopes.

(iii) x , the average monthly demand of the product, and y , the average monthly price of the product.
