3. Use Table 9.1 (OR ANY VALID TECHNIQUE, which might involve z-scores...) to solve the problem. Consider again that the company making tires for bikes is concerned about the exact width of its cyclocross tires. The information is the same as in #1 above. To what level would it have to reduce the standard deviation in the process to meet a defect target of just 0.5%? ANSWER 1. A company making tires for bikes is concerned... A company making tires for bikes is concerned about the exact width of its cyclocross tires. The company has a lower specification limit of 22.3 mm and an upper specification limit of 23.3 mm. The standard deviation is 0.22 mm and the mean is 22.8 mm. What is the process capability for the process? ANSWER 0.75 (23.3-22.8)/(3x0.22) = 0.75 I
