Suppose you wish to determine the degree to which annual earnings of professional golfers (Earnings) are related to driving distance (Yards Per Drive). The driving distance shows how far a golfer can hit the ball after it hits the ground. You were given the Excel output below. If the image below is not clear, dowload a copy here.

Would you please assist in answering this question with working out?Thank you. Q. Using a sample of recent university graduates, you estimate a simple linear regression using initial annual salary as the dependent variable and the graduate's weighted average mark (WAM) as the explanatory variable. If the regression model has an estimated intercept of 2200 and an estimated slope coefficient of 550, what is the predicted starting salary of a student with a WAM of 82?

In the section we introduced a descriptive measure of the utility of the multiple linear regression for making predictions. a. Define and interpret this descriptive measure. b. Identify the symbol used for this descriptive measure.
True or False and explain if false: 1. The slope estimate from a regression model is an example of descriptive statistic. 2. if a p-value is 0.9, then we may appropriately conclude that no relationship between X and Y exists 3. Assuming that X variable is controlled, one way to decrease standard errors in a sample linear regression analysis is to assign value of X variable that are further apart.

Data for 50 U.S. “states" was used to examine the relationship between violent crime rate (violent crimes per 100,000 persons per year) and the independent variables of urbanization (percentage of the population living in urban areas) and poverty rate. 50 observations were examined. The Excel sheet output for the analysis of this data is shown in the Figure (with some information intentionally left blank).
