You are a supervisor at Regional Call Center’s Washington, DC, facility. Regional provides contract call center services for a number of companies, including banks and major retail companies. You have been with the company for slightly more than seven years, having joined Regional right after graduating with a master’s degree in business administration from Strayer University. After the monthly staff meeting, you were handed a new assignment by the company CEO. The assignment came out of a discussion at the meeting in which one of Regional’s clients wanted a report describing the calls being handled for them by Regional. The CEO had asked you to describe the data in a file attached called Regional Call Center and produce a report that would both graphically and numerically analyze the data. The data are for a sample of 57 calls and for the following variables:

• Account Number.
• Past Due Amount.
• Current Account Balance.
• Nature of Call (Billing Question or Other).

## Instructions

2. Develop bar charts showing the mean and median current account balance.
3. Construct a scatter diagram showing current balance on the horizontal axis and past due amount on the vertical axis.
4. Compute the key descriptive statistics for current and past due amount.
