    Experience raising New Jersey Red chickens revealed the mean weight of the chickens at five
    months is 4.35 pounds. The weights follow the normal distribution. In an effort to increase their
    weight, a special additive is added to the chicken feed. The subsequent weights of a sample of
    five-month-old chickens were (in pounds):
    4.41 4.37 4.33 4.35 4.30 4.39 4.36 4.38 4.40 4.39
    At the .01 level, has the special additive increased the mean weight of the chickens?
    Estimate the p-value.
