An ethanol railroad tariff is a fee charged for shipments of ethanol on public railroads. an agricultural association publishes tariff rates for railroad-car shipments of ethanol. assuming that the standard deviation of such tariff rates is $1300, determine the probability that the mean tariff rate of 500 randomly selected railroad-car shipments of ethanol will be within $80 of the mean tariff rate of all railroad-car shipments of ethanol. interpret your answer in terms of sampling error.
