Question: More on constructing a p chart for damaged eggs. Refer to Exercise. Suppose that there are two machine operators, each working four-hour shifts. The first operator is very skilled and can inspect 500 eggs per hour. The second operator is less experienced and can inspect only 400 eggs per hour. Construct a p chart for an eight-hour day showing the appropriate center line and control limits.
Exercise: Constructing a p chart for damaged eggs. An egg farm wants to monitor the effects of some new handling procedures on the percent of eggs arriving at the packaging center with cracked or broken shells. In the past, 1.89% of the eggs were damaged. A machine will allow the farm to inspect 500 eggs per hour. What are the initial center line and control limits for a chart of the hourly percent of damaged eggs?
