If customer tolerances are measured using specificaton limits around a target, which of the statements are incorrect; 1. Customers perceive some qualtiy loss if the process is off target but within the specification limits. 2. Customers perceive a quality loss that increases exponentially the further the process is off target 3. Customers perceive a quality loss that increases quadratically the further the process is off the target 4. Customers perceive no quality loss if the process if off target bus within the specification There are 2 incorrect answers. This is following a normal distribution
Based on data from the U.S. Bureau of Public Roads, a model for the total stopping distance of a moving car in terms of its speed is s = 1.1v+ 0.054v2, where s is measured in ft and v in mph. The linear term 1.1y models the distance the car travels during the time the driver per-ceives a need to stop until the brakes are applied, and the quadratic term 0.054y2 models the additional braking distance once they are applied. Find ds/dv at v = 35 and v = 70 mph, and interpret the meaning of the derivative.
