1. The cost of quality are given by the following equations:
Ca = 100D + 1500
Cp = -50D + 6300
Cf = De0.5D
Where:
Ca is the cost of appraisal,
Cp is the cost of prevention, and
Cf is the cost of failure.Ca = 100D + 1500
Note that D is the percent defectives and 0 < D < 100.
Determine the total cost of quality when there are no defectives. D=0 and product quality is perfect.
2. Given the information in Problem 1, determine the total cost of quality when D=90. No company could stay in business with D=90, as will be apparent from the calculations.
3. Given the information in problem 1, determine the total cost of quality when D=0,10, and 15. Plot all the points.

Using the the QMpom module called Forecasting Models (Linear Regression), analyze the effect of the day on the number of rejects in each sample. Also, use the QMpom module called Quality Control Models (Statistical Quality Control (SQC)) will help create the p chart.
A food processor specified that the contents of a jar of salsa should weigh 14+ 0.10 ounces net. A statistical quality control operation is set up, and the following data are obtained for one week:
___________________Sample No._______________
1 - Mon 14.10 14.06 14.25 14.06
2 - Tues 13.90 13.85 13.80 14.00
3 - Wed 14.40 14.30 14.10 14.20
4 - Thurs 13.95 14.10 14.00 14.15
5 - Fri 14.05 13.90 13.95 14.60
Using the QMpom module called Forecasting Models (Linear Regression), analyze the effect of the day on the sample means for the weight of the contents of the salsa jars.
A) Construct and x- chart based on these 5 samples
B) Construct an R- chart based on these 5 samples
C) What points, if any, have gone out of control?
D) Discuss the results.
