Textbook Question

Chapter 10.5, Problem 5E

A process has a process capability index of C_p = 1.2.

a. Assume the process mean is set to its optimal value. Express the upper and lower specification limits in terms of the process mean and standard deviation.
b. Using the normal curve, estimate the proportion of units that will be nonconforming.
c. Is it likely or unlikely that the true proportion of nonconforming units will be quite different from the estimate in part (b)? Explain.

Features Features Normal distribution is characterized by two parameters, mean (µ) and standard deviation (σ). When graphed, the mean represents the center of the bell curve and the graph is perfectly symmetric about the center. The mean, median, and mode are all equal for a normal distribution. The standard deviation measures the data's spread from the center. The higher the standard deviation, the more the data is spread out and the flatter the bell curve looks. Variance is another commonly used measure of the spread of the distribution and is equal to the square of the standard deviation.
