### Problem: Customers are Complaining about Sandwich Length You are the owner of three local sandwich shops. Recently, you’ve received complaints from customers that their “footlong” sub sandwiches were less than 12 inches long. To address this quality concern, data was collected on all footlong sub sandwiches made over a period of one hour at each store. Determined which, if any, of your stores are making sub sandwiches that are significantly shorter than 12 inches. You will conduct three t-tests, one for each store. You want to be 95% confident in your results. (Note: This case is inspired by reality. Search the internet for "claims over footlong sub" for a historical perspective and how a company used statistics to ensure consistent quality.) ### Sandwich Measurements (in inches) | Store 1 | Store 2 | Store 3 | |---------|---------|---------| | 8.8 | 9.1 | 9.0 | | 10.4 | 11.6 | 9.2 | | 12.5 | 11.2 | 10.1 | | 11.6 | 11.9 | 12.7 | | 14.1 | 11.8 | 11.6 | | 12.4 | 10.8 | 12.3 | | 11.6 | 8.7 | 13.1 | | 13.4 | 13.1 | 12.8 | | 10.4 | 10.2 | 13.2 | | 12.0 | 11.3 | 8.8 | | 9.7 | 12.0 | 10.7 | | 11.4 | 10.5 | 8.3 | | 11.8 | 6.4 | 11.7 | | 12.4 | 9.2 | 11.4 | | 8.6 | 8.6 | 11.6 | | - | - | - | | - | - | - | | - | - | - | ### Statistics |
