... attention in school. Anyhow, you think that a new type of organic feed may lead to plumper chickens. As every chicken farmer knows, a fat chicken sells for more than a thin chicken, so you are excited. You know that a chicken on standard feed weighs, on average, 3 pounds. You feed a sample of 25 chi ...
