1. 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 for line items was observed: 5 7 5 12 5 7 6 A 6 9 2 8 4 9 8 2 5 8 6 5 10 3 5 6 4 a) For the above frequency distribution, calculate the number of classes and the class width. b) Using the information collected in a, create a frequency distribution table where the starting value is a multiple of the class width. Remember to include the class limits, frequency, and relative frequency for the classes. c) Using the information from part a, construct the following graphs electronically and remember to properly label your graphs. i) bar graph iii) histogram using midpoints ii) pie graph iv) frequency polygon
