(2 points) When a poultry farmer uses his regular feed, the newborn chickens have normally distributed weights with a mean of 61.3 oz. In an experiment with an enriched feed mixture, ten chickens are born with the following weights (in ounces). 61.5, 64.4, 66.4, 67.7, 66.2, 65, 65.8, 64.9, 66.7, 65.3 Use the a = 0.01 significance level to test the claim that the mean weight is higher with the enriched feed. (a) The sample mean is x = (b)...
