Question: A shipping company believes that the variation in the cost of a customer's shipment can be explained by differences in the weight of the package being shipped. To investigate whether this relationship is useful, a random sample of 20 customer shipments was selected, and the weight (in lb) and the cost (in dollars, rounded to the nearest dollar) for each shipment were recorded. The following results were obtained:
