Estimate the regression line of food expenditure on income.
Suppose you have a large, random sample of the variables Y and X. You then regress Y on X and get the following results (with standard errors in parentheses):
Y=16.8-3.9x
(3.8) (1.2)
The numbers 16.8 and -3.9 are the realized values for the intercept and slope (respectively) of the regression equation describing the sample, which are consistent estimators for what population parameters?
The intercept and slope (respectively) of the sample determining function. The intercept and slope (respectively) of the regression equation that best fits the population.
Instructions: Enter your responses rounded to three decimal places. If you are entering any negative numbers be sure to include a negative sign (-) in front of those numbers:
b. Provide a 99% confidence interval for each estimator's corresponding population parameter:
Intercept: Slope:(------------) (-------------)
Slope (-------------) (------------------)
What do you mean by the Sampling Distribution of the OLS Estimators in Multiple Regression?

- Sherwin-Williams Company is attempting to develop a demand model for its line of exterior house paints. The company’s chief economist feels that the most important variable affecting paint sales (Q) (measured in gallons) is the Selling price (P) (measured in Ghana cedis per gallon). The chief economist decides to collect data on the variables in a sample of 10 company sales regions that are roughly equal in population. Data on paint sales, and selling prices were obtained from the company’s marketing department.

This study analyzes the effect of celebrity endorsement on customer’s attitude toward brand as well as the effect of customer’s attitude toward brand on customer’s purchase intention in Vietnam. A survey was conducted with 306 individuals in Vietnam. After conducting the explanatory factor analysis (EFA), and multi-variable regression analysis, results indicate that customer’s attitude toward brand is positively affected by 03 factors: celebrity match-up congruence with the brand/product, celebrity trustworthiness, and celebrity expertise. Attitude toward brand also has a positive impact on customer’s purchase intention.
