construct an OC curve for a X chart with 25 s limits and a s

construct an OC
curve for a X  chart with 2.5 s limits and a sample size of 10 using increments Dks = 0.5.Compare with the OC curve developed for sample size of 5 and, based on the OC curve, suggest which sample size would be better for identifying when a process change has occurred.
