A random variable is normally distributed with a mean of μ = 50 and a standard deviation of a = 10. (a) The following figure shows that the normal curve almost touches the horizontal axis at three standard deviations below and at three standard deviations above the mean (in this case at 20 and 80).

Suppose the weight of pieces of passenger luggage for domestic airline flights follows a normal distribution with u = 24 pounds and o = 6.3 pounds. (a) Calculate the probability that a piece of luggage weighs less than 28.8 pounds. (Assume that the minimum weight for a piece of luggage is 0 pounds.) (b) Calculate the weight where the probability density function for the weight of passenger luggage is increasing most rapidly. Ib (c) Use the Empirical Rule to estimate the percentage of bags that weigh more than 11.4 pounds. % (d) Use the Empirical Rule to estimate the percentage of bags that weigh between 17.7 and 36.6. % (e) According to the Empirical Rule, about 84% of bags weigh less than pounds.
