A Moving Average chart is constructed to detect small mean shifts for a manufacturing process, which has moving window size w = 3, and sample size n = 3. If at sampling time t = k (k > 3), the process meanshifts from (m0) to (m0+ sigma) and keeps it afterwards. Please calculate the detection power at sampling time k, k + 1, k + 2, and comment what will be the detection power after time k + 2.
