In Problem 12.7 on page 424, you used the plate gap on the bag-sealing equipment to predict the tear rating of a bag of coffee (stored inStarbucks). Using the results of that problem,
A.determine the coefficient of determination,r2, and interpret its meaning.
B.determine the standard error of the estimate.
C.How useful do you think this regression model is for predicting the tear rating based on the plate gap in the bag-sealing equipment?
