(29) In the article “In the Soup: A Case Study to Identify Contributors to Filling Variability,” Hare (1988) considers the problem of trying to determine the variables which affect the filling variability of dry soup mix. Five different variables where considered: (A) number of filling ports being used in the mixer; (B) the operating temperature; (C) the mixing time in seconds; (D)

the batch weight in pounds (lbs.); and (E) the delay between mixing and packaging. The operating temperature was maintained using a cooling jacket:

either the cooling jacket was on (denoted by C) or the process was operated at ambient conditions (denoted by A). The results are shown in Table 4.12. Run 7 is the normal operating conditions. The results are presented in the order in which they were run. Perform the following analysis of this data set:
