Starbucks Coffee Co. uses a data-based approach to improving quality and customer satisfaction. An experiment was conducted to determine the factors in the bag-sealing equipment that might be affecting the ease of opening the bag without tearing the inner liner of the bag. Among the factors that could affect the rating of the ability of the bag to resist
tears were the viscosity, pressure, and plate gap on the bag-sealing equipment. The accompanying data were collected on 18 bags in which the plate gap was varied. Develop a multiple regression model that uses the viscosity, pressure, and plate gap on the bag-sealing equipment to predict the tear rating of the bag. Do you think that you need to use all
three independent variables in the model? Explain.
