Imagine you wanted to guess the number of cans of the soup sold in a month for another, similar store in town that was not included in these data. Based on your answer to 9., which of the following would be the best way to make this guess? Check one. C] Use the equation and plug in the number of facings for this product in that store. C) Use the mean number of cans sold in the other stores, which is 28 .7". 12. Calculate the coefcient of determination. What does this value mean? Check one: C It is the proportion of the variability in the number of cans of soup sold that CAN be accounted for by the variability in the number of facings. D It is the proportion of the variability in the number of cans of soup sold that CANNOT be accounted for by the variability in the number of facings. D It is the proportion of the variability in the number of cans of soup sold and the number of facings that is due to chance
