(2 points) When a poultry farmer uses his regular feed, the newborn chickens have normally distributed weights with a mean of61.1

61.1oz. In an experiment with an enriched feed mixture, ten chickens are born with the following weights (in ounces).

63.5,63.9,66.1,61.9,66.4,65,65,68.3,65.3,66.9

63.5,63.9,66.1,61.9,66.4,65,65,68.3,65.3,66.9

(e) The conclusion is

A.There is not sufficient evidence to support the claim that with the enriched feed, the mean weight is greater than 61.1.

B.There is sufficient evidence to support the claim that with the enriched feed, the mean weight is greater than 61.1.
