problem 1:
a) The regression outcomes for the quantity demanded of good X is given by:
ln Q_{X} = 1220 – 9.5 ln P_{X} – 2.21 ln P_{Y} + 1.01 ln M
t values (5.3) (-5.12) (-2.15) (5.41)
Adjusted R^{2} = 0.96 F statistics = 160.20 P value = 0.001
Here Q_{X} is the quantity demanded of X, P_{X} is the price of X, P_{Y} is the price of Y and M is the consumer income. Assess the above regression and describe how such results might be helpful to a manager.
