CASE: Century National Bank
Assume that you work in the Planning Department of the Century National Bank and report
to Ms. Lamberg. You will need to do some data analysis and prepare a short written report.
Remember, Mr. Selig is the president of the bank, so you will want to ensure that your report
is complete and accurate.
Century National Bank has offices in several cities in the Midwest and the southeastern part
of the United States. Mr. Dan Selig, president and CEO, would like to know the
characteristics of his checking account customers. What is the balance of a typical customer?
How many other bank services do the checking account customers use? Do the customers use
the ATM service and, if so, how often? What about debit cards? Who uses them, and how
often are they used?
To better understand the customers, Mr. Selig asked Ms. Wendy Lamberg, director of
planning, to select a sample of customers and prepare a report. To begin, she has appointed a
team from her staff.
You are the head of the team and responsible for preparing a report. You select a random
sample of 60 customers. In addition to the balance in each account at the end of last month,
you determine: (1) the number of ATM (automatic teller machine) transactions in the last
month; (2) the number of other bank services (a savings account, a certificate of deposit, etc.)
the customer uses; (3) whether the customer has a debit card (this is a relatively new bank
service in which charges are made directly to the customer’s account); and (4) whether or not
interest is paid on the checking account. The sample includes customers from the branches in
Cincinnati, Ohio; Atlanta, Georgia; Louisville, Kentucky; and Erie, Pennsylvania.

interval, and ratio) and by the type of variable (Categorical or Numerical, then discrete or
