Chapter 16, Problem 33SE
Refer to the data in exercise 31.
- a. Develop an estimated regression equation that can be used to predict Delay by using Industry and Quality.
- b. Plot the residuals obtained from the estimated regression equation developed in part (a) as a
function of the order in which the data are presented. Does any autocorrelation appear to be present in the data? Explain. - c. At the .05 level of significance, test for any positive autocorrelation in the data.

A quality characteristic of a product is normally distributed with mean μ and standard deviation σ = 1. Speci-
fications on the characteristic are 6≤x≤8. A unit that falls within specifications on this quality characteristic
results in a profit of Co. However, if x 8, the profit is -C2. Find the value
ofμ that maximizes the expected profit.
A) The output voltage of a power supply is normally distributed with mean 5 V and standard deviation 0.02 V. If
the lower and upper specifications for voltage are 4.95 V and 5.05 V, respectively, what is the probability that a
power supply selected at random conform to the specifications on voltage?
B)
Continuation of A. Reconsider the power supply manufacturing process in A. Suppose
We wanted to improve the process. Can shifting the mean reduce the number of nonconforming units produced?
How much would the process variability need to be reduced in order to have all but one out of 1000 units conform
to the specifications?
