Hotelling T2 - Multivariate Problem: The data shown in Table from a production process with two CTQs, X1, and X2. The sample data are sample means of X1 and X2 (Sample size =25, Assume that mean values of the quality characteristics and the covariance matrix were computed from 50 preliminary Samples=50). Construct T2 control chart using these data for Phase II. 55 (200 D 130 ? Xdbar = 0 S= S-1= D D D 304 (130 D 120/ ? Total no. of CTQ (P)? Sample Size (n)? Subgroup (m)?
