The data shown in Table 11.E1 come from a production process with two observable quality characteristics: x1 and x2. The data are sample means of each quality characteristic, based on samples of size n -= 25. Assume that mean values

The data shown in Table 11.E1 come from a production process with two observable quality characteristics: x1 and x2. The data are sample means of each quality characteristic, based on samples of size n -= 25. Assume that mean values of the quality characteristics and the covariance matrix were computed from 50 preliminary samples:
The data shown in Table 11.E1 come from a production

Construct a T2 control chart using these data. Use the phase II limits.
