ABC Corporation makes cardboard boxes. Forty-five randomly selected such boxes were loaded until they broke. The average breaking capacity of these boxes was found to be 78.52 pounds. Suppose that the sample standard deviation of the breaking capacities of such boxes is 2.63 pounds and population distribution is leftward skewed. Calculate a 95% confidence interval for the average breaking capacity of all boxes of this type. Draw graph ABC Corporation makes cardboard boxes.
