In order to improve the production time, the supervisor of assembly lines in a manufacturing setting of cellular phones has studied the time that it takes to assemble certain parts of a phone at various stations. She measures the time that it takes to assemble a specific part by 165 people at different shifts and on different days. The record of her study is organized and shown in the accompanying table.
