Reference no: EM13107449

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

4.20

4.39

4.36

4.38

4.40

4.39

At the .01 level has the special additive increased the mean weight on the chickens? Estimate the P-values.
