Question:
A shirt manufacturer buys cloth by the 100-yard roll from a supplier. For setting up a control chart to manage the irregularities (e.g., loose threads and tears), the following data were collected from a sample provided by the supplier.
Using these data, set up a c-chart with z = 2.
Suppose the next five rolls from the supplier had three, two, five, three, and seven irregularities. Is the supplier process under control?
