Historically, the average time to service a customer complaint has been $3$ days and thestandard deviation has been $0\mathrm{.}50$ day. Management would like to specify the control limits for anchart with a sample size of $10-$ and $3-$ sigma limits$.$ Suppose the next sample of $10$ yielded thefollowing result: $3\mathrm{.}2,2\mathrm{.}1,3\mathrm{.}6,2\mathrm{.}8,3\mathrm{.}9,3\mathrm{.}5,2\mathrm{.}7,4\mathrm{.}1,2\mathrm{.}6,$ and $3\mathrm{.}3.$ What conclusion can be drawn?A$)$ Assuming the process variability is in control, the process average is also in statistical control.B$)$ Assuming the process average is in control, the process average is out of statistical control.C$)$ The sample size should be increased.D$)$ No conclusion can be drawn because there is insufficient data.
