Historically, the average time to service a customer complaint has been 3 days and the standard deviation has been 0.50 day. Management would like to specify the control limits for an -chart with a sample size of 10- and 3-sigma limits. Suppose the next sample of 10 yielded the following result: 3.2, 2.1, 3.6, 2.8, 3.9, 3.5, 2.7, 4.1, 2.6, and 3.3. What conclusion can be drawn?
◦ Assuming the process variability is in control, the process average is also in statistical control.
◦ The sample size should be increased.
◦ Assuming the process average is in control, the process average is out of statistical control.
◦ No conclusion can be drawn because there is insufficient data.
