A company manufactures small metal brackets. They are packaged in containers of 1000 brackets each. At the unloading facility, 10 containers have arrived and 36 brackets are selected at random from each container. The fraction non-confirming in each sample is 0.0, 0.0, 0.0, 0.01, 0.02, 0.02, 0.06, 0.0, 0.0 and 0.0. (i) Do the data from this shipment indicate statistical control?

(ii) What is the minimum sample size that would give a positive lower control limit for this chart?

I tried to attempt this question by using the p-chart to determine statistical quality control.
