A large paint retailer has had numerous complaints from customers about underfilled paint cans. As a result, the retailer has begun inspecting incoming shipments of paint from suppli- ers. Shipments with underfill problems will be returned to the supplier. A recent shipment contained 2,440 gallon-size cans. The retailer randomly selected 50 cans and weighed each on a scale. The average weight of the 50 cans was recorded to estimate the average weight of all 2,440 cans. Properly filled cans weigh 10 pounds. (a) What is the population? (b) What is the sample?
