The data below are a random sample of weight gains (pounds) of pigs during a period of 20 days. The farmer was feeding his pigs Purina Pig Chow. The package says that the company guarantees. a minimum pig weight gain of 2.25 lbs/day. Can the farmer show that his pigs have not statistically met that weight gain minimum?
