A certain brand of jelly beans is made by Jelly Belly Inc. The company claims that each package contains about the same number of beans. The packages are filled with an average of 375 jelly beans with a standard deviation of 8. A researcher believes that the number of jelly beans going into each package is less than 375. She purchases 16 packages, counted the number of jelly beans in these packages and found an average of 368 jelly beans with a standard deviation of 10.
