Each month, an American household generates an average of 27.5 pounds of newspaper for garbage or recycling. Assume the standard deviation is 3.1 pounds. If a household is selected at random, find the probability of its generating between 24.3 and 31.9 pounds per month. Assume the variable is approximately normally distributed.
