wuestions A process engineer is trying to determine how the yield of an adhesive application process can be improved by adjusting three process parameters; mixture ratio (A), curing temperature (B), and curing time (C). For each of these input parameters, two levels will be defined for use in this 2-level experiment and the output response monitored is process yield. The data were gathered by performing two replications (n=2) per combination treatment as in Table 3. Table 3: Data for the experiment to improve yield of an adhesive application process Factors Replicate B I II Test A I - 4 4 1 2 + 5 4 3 + 15 19 4 + + + 27 25 5 + + 9 7 6 + + 10 12 7 + + + 22 23 8 + + 30 26 a) b) Calculate all the main effects and interaction effects Analyse the three factors using ANOVA. Do any of the three factors affect the process yield? Use a=0.05. What combination of factor levels produces the highest yield? wuestions A process engineer is trying to determine how the yield of an adhesive application process can be improved by adjusting three process parameters; mixture ratio (A), curing temperature (B), and curing time (C).
