# Estimating the P-Value of a Sample

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.

#### Solution Preview

In this question we will be using the t test, n = 10

the hypothesis test is:

H0: u; less than or equal to ; 4.35

H1: u; > 4.35

next find the mean and standard ...

#### Solution Summary
