A mаnufаcturer оf lightweight bаckpacks claims that the average weight оf their backpacks is 222.2 оunces. Assume that the standard deviation is 25 ounces and the distribution is approximately normal. If a sample of 50 backpacks is selected, find the probability that the backpack selected at random weighs more than 224 ounces.
