please answer all question fully
Statistical Analysis: The regression output presented on the next page was obtained from regressing the dependent variable Y on the independent variable L. The variable Y is real gross domestic product measured in billions of year 2009 dollars. The labor variable L is the number of full time equivalent employees measures in thousands of employees 5. Present these regression results in a professional manner, as demonstrated in class. (10 points) Provide an economic interpretation of...

4. Let’s compare the results you calculated for Q3b with results from a multiple linear regression. 4a. Would additionally controlling for ‘depth’ and ‘latitude’ be helpful? In other words, is a model that includes ‘depth’, ‘latitude’ and ‘longitude’ superior in model fit to a model that includes only ‘longitude’? Output for a multiple linear regression which includes longitude, depth, and latitude is provided below. (2 points) 4b. Interpret the parameter estimate for ‘longitude’ from the multiple linear regression output. (1...

I have to complete a multiple regression analysis using the
quantity of coal as the dependent variable with the price and GDP
as the independent variables. The problem I am having is that when
I perform the regression analysis I can't get the Price to be
negative and the GDP to be positive. I am attaching the spreadsheet
for your reference. Any assistance you can provide will be greatly
appreciated.

You were asked by your manager to evaluate the regression tables below to decide which cost driver would be best to use for the production department. Since your manager is new and does not understand the regression analysis tables, you will need to explain why one set of statistics is better than the other and why you have chosen the better driver.
