Rochelle contacted a company that produced electric motors and vector drives, and its consultants told her that it would be possible to set up an experiment that would allow her to estimate whether the new process could increase production. Rochelle began to plan for the test. She decided that once the new equipment was in place and the workers were trained in the new process, the equipment would run for 50 days. Each day's output would be recorded. She also collected similar data from a sister plant in Birmingham which continued to use manual labor to move the bricks. Rochelle needs to prepare a report that analyzes the data for the test period at the Memphis plant. The financial analysts at Duro headquarters believe the purchase can be justified if the equipment will lead to an average increase in production of at least 10,000 bricks per day. She intends to use the data from the Birmingham plant as the basis for comparison.

Memphis

Total Bricks Produced in 50 days: 7,484,500

standard deviation: 3402.46

Birmingham

Total Bricks Produced in 50 days: 6,902,350
