ECO - Pilgrim Bank case

Your discussion assignment this week is associated with the Pilgrim Bank case. Using the attached file, answer the following questions:
A. Is there a difference in profitability across regular vs. online customers?

B. How should we deal with the missing data?

C. Using a regression model, is there a difference in profitability across the two customer types and if so, how much are the more profitable customers worth to the bank?

You must show any calculations, empirical information, etc. as part of your post, NOT as an attachment. You also must show enough so that someone reading your post will be able to replicate what you did.
