We employed regression analysis to specify the extent to which the independent variables predicted the dependent variable. The analysis conducted in this study was therefore intended to test the hypotheses of the study. The regression output provided some measures which allow assessment of the hypotheses. Following from

recommendations based on regression analysis. The demand curve shows the quantity demanded at each price. Equivalently, the inverse demand curve shows the willingness to pay for the last item at a given quantity. I agree with your regression coefficients of Q = 883223.748 - 25355.71584P and Cost = 3122901 +8.755693 Q. Linear regression is better at interpolating than extrapolating. The prices ranged from 10.99 to 31.99, so we are interpolating between prices of 10.99 and 31.99. The linear regression is less reliable
