Use the information below to answer the next ve questions. Two machines are used to fill 50 pound bags of dog food. A sample of 60 bags filled by Machine A had an average fill of 50.5 pounds with an SD of 3 pounds. A sample of 40 bags filled by Machine B had an average fill of 49.2 pounds with an SD of 4 pounds. We want to know if this is evidence that the average amount of dog food dispensed by Machine A is greater than the average amount dispensed by Machine B. 1.
