1. Analyze the estimated demand function by using the estimated coefficients to discuss the impact of each of the explanatory variables, P, CP, M, and PE, on the quantity of Maa mustard oil demanded. In discussing the impact, consider a one unit change in each variable while holding the others constant.

ANSWER 1 We have presented with the following demand function QD = 3934.25 – 121.15P + 113.49CP – 0.31M + 7.99PE + D Now in this equation of we put other things constant than A 1 rupee increase in price of MAA mustered oil will decrease the Qd by 121.15 kilograms A 1 rupee increase in the price of competitors of MAA mustered oil will increase the Qd by 113.49 kilograms A 1 rupee increase in the income level of the persons will decrease the Qd of MAA mustered by 0n31 kilograms a single rupee increase in the promotional expenses of maa mustard oil will increase the quantity demanded by 7.99 kg
