A random sample of restaurants in Philadelphia was selected for a study. For each restaurant, the number of years in business was recorded. The data for "number of years in business" as follows: 2 3 8 9. 9 10 12 12 13 15 19 21 27 31 33 37 37 38 39 40 40 42 42 44 46 48 In this problem you will analyze the data by creating a histogram using 8 classes. А. Fill in the frequency table below using a class width of 6 (which produces 8 classes). Class Limits Class Boundaries Lower - Upper Class Midpoint Lower - Upper Class Frequency Create a histogram representing the data. Be sure to label all parts of the histogram. C. What is the shape of the distribution? B.
