(Solution) - To estimate the various components of variability in a filtration -(2025 Original AI-Free Solution)

Paper Details

To estimate the various components of variability in a filtration process, the percent of material lost in the mother liquor is measured for 12 experimental conditions. 3 runs on each condition. Three filters and 4 operators are selected at random to use in the experiment, resulting in the following measurements:

(a) Test the hypothesis of no interaction variance component between filters and operators at the a = 0.05 level of significance.
(b) Test the hypotheses that the operators and the filters have no effect on the variability of the filtration process at the a = 0.05 level of significance.
(c) Estimate the components of variance due to filters, operators, and experimental error.
