Question 14 Chapter 6. DO 1-5 QUESTIONS.

a) Establish a control chart for monitoring the average weights of the bowling balls in which the upper and lower control limits are each two standard deviation from the mean. What are the values of the control limits?

1.) Upper Control Likit (UCL x) = ____ Ib. (round your response to two decimal places).

2.) Lower Control Limit (LCL x) = ____ Ib. (round your response to two decimal places).

b) If three standard deviations are used in the chart, what are the values of the control limits?

3.) Upper Control Limit (UCL x) = ___Ib. (round your response to two decimal places).

4.) Lower Control Limit (LCL x) = ___ Ib. (round your response to two decimal places).

5.) How do these values change?

a) The control limits for the 2-sigma x chart and for the 3-sigma x chart are the same

b) The control limits are tighter for the 3-sigma x chart than the 2-sigma x chart

c) The control limits are tighter for the 2-sigma x chart than for the 3-sigma x chart
