The Harris Corporation University of Florida study to determine whether a manufacturing process performed at a remote location can be established locally. Test devices (pilots) were set up at both the old and new locations and voltage readings on 30 production runs at each location were obtained. The data are given in the table attached. a. Compare the mean voltage readings at the two locations using a 95% confidence interval. b. Based on the interval, part a, does it appear that the manufacturing process can be established locally.
