The average time it takes to complete colonoscopy procedure is 45 minutes with a standard deviation of 10 minutes. To monitor this process, samples of 10 patients are taken every month and the mean time computed. Today, 10 patients from a total of 25 colonoscopies was taken. Mean time was 52 minutes. Suppose a second sample of 10 patients was undertaken shortly after the first sample. The mean of both samples would be expected to be the same if the process is in-control.
