Questions:
1. Find the demand for passenger seat (Y) as a function of the fare of the airline(X1), the fare f the competing airline (X2), and the annual per capital income of passengers (X3).
2. Graph the actual and the estimated Y and assess the goodness of fit.
3. State the effects of each of the independent variable on the demand for passengers.
4. State the significance or non significance of each of the independent variables.
5. If the fare of the airline increases to $300 (X1=300), the fare of the competing airline is $200 (X2=$200) and the annual income is (X3=$120), find how many tickets will the airline sell?
