Burger King is one of the largest fast-food franchise operations in the world. Recently, the district manager for Burger King in Las Vegas conducted a study in which she selected a random sample of sales receipts.

She was interested in the number of line items on the receipts. For instance, if a customer ordered two 1/4-pound hamburgers, one side of fries, and two soft drinks, the number of line items would be five. The following data were observed:

7 5 7 6 5 5 4 8 6 5 8 7 6 5 6 2 9 4 4 5 8 4 9 6 6 5 8 9 9 1 6 5 10 6 7 6 5 5 5 6 8 7 6 8 6 6 9 6 12 7 5 6 7 11 4 4 3 4 1 4 11 2 5 5 8 2 3 4 9 6 6 5 8 6 3 6 4 5 8 10
