The weight of checked bags for a major airline can be modeled by a normal curve with mean 35.6 pounds and standard deviation 4.8 pounds. A checked bag that weighs more than 50 pounds is overweight and requires an additional fee. Use the 68-95-99.7 rule to approximate the probability that a randomly selected checked bag is overweight.
