Identify the correct statement(s):
a. In process control by variables, measurements of items produced by a process are taken to determine quality
b. Bar X chart is used to monitor the average measurement of a sample of items produced by a process
c. R chart is used to monitor the range of measurements of a sample of items produced by a process
d. All the above statements are correct
Homework Answers
Answer: d. all the above statements are correct
Explanation:
a. Quality of the product or capability of the process has been determined by using various measurements like mean, range, defect etc. to check whether process is in control or not
b. X-bar chart is used to monitor mean or average of the sample of items and check whether any observation is out of control limits or not
c. In the same way, R-bar chart is used to monitor range of the observations of sample.

4. (5 Points) Control charts are to be kept on the thickness measurements for the process that produces steel tubing. The current specifications on the tubing are 0.1340 +0.0010 inch. After collecting 25 rational samples of size n 4 measurements at approxi half-hour intervals, the data were used to determine the sum of sample averages as 4.014 inches and the sum of sample ranges as 0.027 inch. Using X-bar and R control charts the process was declared in-control. Assume that...

The management of the Diners Delight restaurant chain is in the process of establishing quality control charts for the time that its service people give to each customer. Management thinks the length of time that each customer is given should remain within certain limits to enhance service quality. For simplicity, the data from three samples are displayed below. In each sample, four service people were randomly selected, and the customer service they provided was observed. The time (in seconds) to...
