Count Chocula Cereal. Filling boxes with consistent amounts of its cereals is critical to General Mills’s success. The filling variance for boxes of Count Chocula cereal is designed to be .02 ounces2 or less. A sample of 41 boxes of Count Chocula shows a sample standard deviation of .16 ounces. Use a = .05 to determine whether the variance in the cereal box fillings is exceeding the design specification.
