# Suppose that following the construction of the x and R control charts in Exercise 6.34, the process engineers decided to change the subgroup size to n = 2. Table 6E.16 contains 10 new subgroups of thickness data. Plot this data

Suppose that following the construction of the x and R control charts in Exercise 6.34, the process engineers decided to change the subgroup size to n = 2. Table 6E.16 contains 10 new subgroups of thickness data. Plot this data on the control charts from Exercise 6.34(a) based on the new subgroup size. Is the process in statistical control?
