When a poultry farmer uses his regular feed, the newborn chickens havenormally distributed weights with a mean of 61.4 oz. In an experiment with anenriched feed mixture, ten chickens are born with the following weights (in ounces).65.7, 61.5, 67, 64.1, 67.7, 64.2, 67.1, 66.4, 65.3, 63.4Use the a = 0.05 significance level to test the claim that the mean weight is higherwith the enriched feed.The sample mean is a =The sample standard deviation is s =Select the correct null and alternative hypotheses:Ο Α.

There is sufficient evidence to support the claim that with the enriched feed,the mean weight is greater than 61.4.

There are 10 sample observations. Thus, n = 10.The sample mean is,The sample mean is, x¯=65.24.
