A molding machine that contains different cavities is used in producing plastic parts. The product characteristics of interest are the product length (in.) and weight (g). The mold cavities were filled with raw material powder and then vibrated during the experiment. The factors that were varied were the vibration time (seconds), the vibration pressure (psi), vibration amplitude
a. Develop the most appropriate multiple regression model to predict the length in cavity 1. Be sure to perform a through residual analysis. In addition, provide a detailed explanation of your results.
b. Repeat (a) for cavity 2.
c. Compare the results for length in the two cavities.
d. Develop the most appropriate multiple regression model to predict the product weight in cavity 1. Be sure to perform a thorough residual analysis. In addition, provide a detailed explanation of your results.
e. Repeat (d) for cavity 2.
f. Compare the results for weight in the two cavities.
