Question

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 average
weight, in pounds, of nine of the bowling balls produced that day
has 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 these
values change? Why?
