Parts Manufactured by an Injection Molding Process Are Subjected to a Compressive

question 66

Multiple Choice

Parts manufactured by an injection molding process are subjected to a compressive strength test.We monitor the compressive strength of the parts manufactured by this process using an and an s control chart.Samples of size 9 are taken at regular intervals,and their mean compressive strength (in psi = pounds per square inch) and standard deviation are plotted on the charts in time order.The overall mean of the sample means is = 81.2 psi,and the mean of the sample standard deviations is = 2.9 psi.The control chart constants are (partially) reproduced below. What is the lower control limit for the chart?

• A)0 psi
• B)18.8 psi
• C)78.2 psi
• D)78.7 psi
