For a certain brand of canned corn, the company claims that the mean weight of the contents of the cans is 15.25 ounces. A random sample of 36 cans were selected.

A hypothesis test will be conducted to investigate whether there is evidence to support the belief that the mean is less than 15.25 ounces.
