Starbucks coffee uses a data-based approach to improve the quality and customer satisfaction of its products. When survey data indicated that Starbucks needed to improve its package sealing process, an experiment was conducted to determine the factors in the bag stealing equipment that might affect the ease of opening the bag without tearing the inner lining of the bag. One factor that could affect the rating of the ability of the bag to resist tears was the plate gap on the bag sealing equipment.? Data was collected on 19 bags of coffee in which the plate gap was varied. The results are stored in the Starbucks file attached. Answer the following questions (A-E) below:A) construct a scatter plot.?B) assuming a linear relationship, use the least-squares method to determine the regression coefficients b0 and b1?C) interpret the meaning of the slope, b1, in this problem.D) predict the mean tier rating when the plate gap is equal to 0.?E) what should you tell management of Starbucks about the relationship between the plate gap and the tear rating??
