A linear demand regression model found the following:

Ordinary Least Squares Estimates
________________________________________

Dependent Variable : QUANTITY

Independent variable: Coefficient t-statistic

Constant 10 2.5

- PRICE -2 1.3

- INCOME 3 4.0

Observations 35

Estimated F = 7.960

Critical t value (95% Confidence Level) 2.042

Critical F value (95% Confidence Level) 4.17

- Write the demand function as an equation (quantity as a function of price)
- Explain the relationship between each independent variable and quantity demanded.
- If Price = 5 and Income = 12, what is the predicted quantity sold?
- Using 95% confidence level criterion, which independent factors have an influence on demand?
- Test the hypothesis that the coefficient of Income is equal to 0. Can you reject this hypothesis?
- What share of overall variation in demand is explained by the regression equation?
- What share is left unexplained?
