Using checking account as the dependent variable and using the number of ATM transactions, the number of other services used, whether the individual has a debit card, and whether interest is paid on the particular account as independent variables, write a report indicating which of the variables seem related to the account balance and how well they explain the variation in account balances. Should all of the independent variables be used in the analysis or can some be dropped? Did you notice any indications to multicollinearity, heteroscedasticity or to autocorrelation?
