Youdriveout is a chain of used car dealers. alicia, the chief financial officer, and john, the controller, are looking at their sales and loan data to brainstorming on how to improve their financial performance. john would like to see some analysis of the profit. for example, how much profit generated by each dealer? which type of car contributed to the most profit? and what other factors also affect the profit? since most of the customers applied for a loan when purchasing the car, alicia also wants to know whether switching the minimum credit score cutoff from 430 to 450 will increase loan currency, which is the proportion of payments that their customers make on loans. so she wants to compare the loan currency rates of the customers whose credit scores are less than 430, between 430 and 450, and higher than 450. she also wants to know whether this change will have any impact on profit.
