An automatic filling machine is used to fill 1-liter bottles of cola. The machine's output is approximately normal with a mean of 0.93 liters and a standard deviation of 0.02 liter. Output is monitored using means of samples of 29 observations. Use z-tables to answer the question. (a) Determine the standard error of the mean. (round your answer to 5 decimal places) s.e. = (b) Determine upper and lower control limits that will include roughly 97 percent of the sample means when the process is in control.

An automatic filling machine is used to fill 1-liter bottles of cola. The machine’s output is approximately normal with a mean of 1.0 liter and standard deviation of .01 liter. Output is monitored using means of samples of 25 observations. Determine upper and lower control limits that will include roughly 97% of the sample means when the process is in control. Using Appendix B, Table A to find the value of Z corresponding to the mean control limits.
A large national producer of cookies and baked goods uses a c chart to monitor the number of chocolate chips in its chocolate chip cookies. The company would like to have an average of six chips per cookie. One cookie is sampled each hour. The results of the last 12 hours were (given) a. Assuming a target value of c = 6, what are the upper and the lower control limits for a c chart?b. Are the 12 observations consistent with a target value of c = 6? If those 12 observations constitute a baseline, what upper and lower control limits result? (Use the normal approximation for your calculations.)

A decrease in both the mean and variation is desirable c. The optimum mean may be lower or higher than current values d. The mean is not as important as the variation
A Quality Analyst wants to construct a control chart for determining whether three machines, all producing the same product, are under control with regard to a particular quality variable. Accordingly, he sampled four units of output from each machine, with the following results : Machine #1 measurements [14, 13, 24, 22]; Machine #2 measurements [ 14, 19, 23, 14]; Machine #3 measurements [ 14, 16, 13, 16].

A Quality Analyst wants to construct a control chart for determining whether three machines, all producing the same product, are under control with regard to a particular quality variable. Accordingly, he sampled four units of output from each machine, with the following results: For upper and lower control limits of 23.29 and 16.71, which machine(s), if any, appear(s) to have an out-of-control process mean?
A quality inspector took five samples, each with four observations (n = 4), of the length oftime for glue to dry. The analyst computed the mean of each sample and then computed thegrand mean. All values are in minutes. Use this information to obtain three-sigma (i.e., z = 3)control limits for means of future times. It is known from previous experience that the standard deviation of the process is .02 minute.SAMPLE1 2 3 4 51 12.11 12.15 12.09 12.12 12.09Observation 2 12.10 12.12 12.09 12.10 12.143 12.11 12.10 12.11 12.08 12.134 12.08 12.11 12.15 12.10 12.12¯X 12.10 12.12 12.11 12.10 12.12

A. Choudhury’s bowling ball factory in Illinois makes bowling balls of adult size and weight only. The standard devia-tion in the weight of a bowling ball produced at the factory is known to be 0.12 pounds. Each day for 24 days, the averageweight, in pounds, of nine of the bowling balls produced that dayhas been assessed as follows: a) Establish a control chart for monitoring the average weights of the bowling balls in which the upper and lower control lim-its are each two standard deviations from the mean. What are the values of the control limits?b) If three standard deviations are used in the chart, how do thesevalues change? Why?
