A certain brand of jelly beans are made so that each package contains about the same number of beans. The filling procedure is not perfect, however. The packages are filled with an average of 275 jelly beans, but the number going into each bag is normally distributed with a standard deviation of 7. If 9 packages are randomly selected, what is the probability that they have an average of between 273 and 277 per package
