Assume that you work in the Planning Department of LTG National Bank and report to Miss G.
You will need to do some data analysis and prepare a short-written report. The written part of the
report should not exceed a page in length. Remember, Mr. K is the President of the bank, so you will
want to ensure that your report is complete and accurate. A copy of the data appears in page 3.

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

of customers and prepare a report. To begin, she has appointed a team from her staff. You are the

On December 17, 2007 baseball writer John Hickey wrote an article for the Seattle P-I about increases to ticket prices for Seattle Mariners
games during the 2008 season. The article included a data set that listed the average ticket price for each MLB team, the league in which the team
plays (AL or NL), the number of wins during the 2007 season and the cost per win (in dollars). The data for the 16 National League teams are shown
below.

The sales manager of a large automotive parts distributor wants to estimate the total annual sales for each of the company’s regions. Five factors appear to be related to regional sales: the number of retail outlets in the region, the number of automobiles in the region registered as of April 1, the total personal income recorded in the first quarter of the year, the average age of the automobiles (years), and the number of sales supervisors in the region. The data for each region were gathered for last year. For example, see the following table. In region 1 there were 1,739 retail outlets stocking the company’s automotive parts, there were 9,270,000 registered automobiles in the region as of April 1, and so on. The region’s sales for that year were $37,702,000.
