For ease of performing the next task, move the variable "Social Networks - Facebook, Twitter, etc" to column A on the spreadsheet. (i.e. Make sure it is the first column in the spreadsheet.) The hiring managers recognize that the funding for one employment source depends on the funding for the other sources. Therefore, they want you to perform a multiple regression predicting Social Network funding from Months 1-12, while controlling for the funding of Billboard, Careerbuilder, Company Intranet - Partner, and Diversity Job Fair. Assume that we know the funding for the the controlled variables for Month 13. They are: Billboard: 520 Careerbuilder: 800 Company Intranet: 0 Diversity Job Fair: 1000 For this model and these known values, what is the predicted value for Social Network funding for Month 13? Question 5 Compare the performance of the model above with a model that just controls for the funding of Billboard. In other words, create a multiple regression predicting Social Network funding from Months 1-12, while controlling for the funding of Billboard. Compare the Regression Statistics. Which model does a better job of explaining the variance in Social Network funding? O The model that just controls for Billboard O The model that controls for Billboard, Careerbuilder, Company Intranet, and Diversity Job Fair

Follow-up Question

For ease of performing the next task, move the variable "Social Networks - Facebook, Twitter, etc" to column A on the spreadsheet. (i.e. Make sure it is the first column in the spreadsheet.)

The hiring managers recognize that the funding for one employment source depends on the funding for the other sources. Therefore, they want you to perform a multiple regression predicting Social Network funding from Months 1-12, while controlling for the funding of Billboard, Careerbuilder, Company Intranet - Partner, and Diversity Job Fair. 

Assume that we know the funding for the the controlled variables for Month 13. They are: 

Billboard: 520

Careerbuilder: 800

Company Intranet: 0

Diversity Job Fair: 1000

For this model and these known values, what is the predicted value for Social Network funding for Month 13?
