Questions 22 - 25 The Tastee company produces baby food. The president of Tastee proposes that her company's product is superior to that of the leading competitor, as babies gain weight faster when their product is used. The company selected a random sample of 60 women who had a one-year old baby. The women fed their baby with Tastee food products for one month. The weight gain of each baby was recorded. The sample mean was 515 grams. The population standard deviation is known and it is 53 grams. At the 5% level of significance, is their enough evidence in the sample to indicate that one-year old babies, who are fed with Tastee food products for one month, gain more than 500 grams? 22.
