As a part of your proposals. you need to submit demographic information to help demonstrate that the location chosen by the management teams will be a good investment. You have collected the following data sample of 2000 customers (specifically. the person paying the bill) on age and gender. (Please note: The bins used were dictated by the proposal review commiittee.)
Genderv/Age> Under 18 18-24 25-45 46-65 Over 65 Total

Female 123 225 384 272 135 1139
Totals 217 401 651 493 238 2000
