Question: The Prescott City Refuge Department has hired a company, Robo Trash Disposal, to pick up trash around the city. The company has indicated it will pick up approximately the same amount of trash each day so that it can cover the entire city within a 3-week period. The City Manager Mike Jones doesn’t believe that the company is fulfilling its contract, and has not been picking up the same amount trash each day. Mike (Mr. Cheapskate) has collected seven weeks of pick-up information for the Robo trucks. (This data is found on data sheet 21 on your data disk.) Does the amount of garbage that is picked up, based on these seven weeks, tend to vary? Support your conclusions using descriptive statistics. (This is not a yes or no question so stretch a little, and actually look at this data before you answer this question.)
