Mark Weiner, an engineer specializes in braking systems is working with several braking system manufacturers: Bosch, Bendix, and Akebono. He is targeting a tolerance of +/9 feet with average (mean) braking distance of 75 feet, for his next generation deluxe model car. Bosch produces an anti-locking braking system, with braking distance average of 78.0 feet, and standard deviation of 2.15 feet. Bendix has a servo braking system, called brake booster; with braking distance average of 80 feet, standard deviation of 1.75 feet. Akebono's system has an average of 77.0 feet, standard deviation of 1.95 feet. a. What is the design tolerance (difference from Upper to Lower Specification Limits), from Mark's specifications. b.
