f a sample of items is taken and the mean of the sample is outside the control limits, the process is:

in control, but not capable of producing within the established control limits.

likely out of control and the cause should be investigated.

within the established control limits with only natural causes of variation.

producing high quality products.

monitored closely to see if the next sample mean will also fall outside the control limits.

    An airline operates a call center to handle customer questions and complaints. The airline monitors a sample of calls to help ensure that the service being provided is of high quality. Ten random samples of 100 calls each were monitored under normal conditions. The center can be thought of as being in control when these 10 samples were taken. The number of calls in each sample not resulting in a satisfactory resolution for the customer is as follows. 4 4...
