Refer to the 2 × 2 plasticizer example in Exercise 4.5. In addition to the eight runs in the study, two runs were made at the current process levels of 45% Ingredient X and 182^C. One run was made at the beginning of the study (reaction time =

h), and the second run was made at the end of the study (reaction time = 6 h). Analyze the example including these two additional runs.

Are the conclusions of the study affected by the new data?
