A mаnаger аt a lоcal Billy Bоb's sandwich shоp knows that right now it takes an average (mean) of 54 seconds to assemble a sandwich. In Dan’s past research, he learned the standard deviation of sandwich production is .7 seconds. Marisol, a new employee, suggested some changes in the process including: rearranging some vegetable locations and changing the order of other ingredients. Marisol is sure her ideas will save time without sacrificing quality. After testing her new methods, the results are: Marisol's new method had a mean assembly time of 52.5 seconds for 10 sandwiches.
