The process mean and developing a control chart

Twenty-five samples, each of size 5, were selected from a process that was in control. The sum of all data collected was 677.5 pounds. What is an estimate of the process mean (in terms of pounds per unit) when the process is in control? Develop a control chart tor this process if samples of size 5 will be used. Assume that process standard deviation is 0.5 when the process is in control, and that the mean of the process is the estimate developed in part (a).
