Question 30

The weight of chicken follows a normal distribution, with a mean of μ pounds and a variance of 4 pounds^2. We took a sample of 144 chicken with a sample mean of 6 pounds. What is the two-sided 95% confidence interval of μ?

Note that from the z-distribution table, we know:

P(Z<= -1.645)="">

P(Z<= -1.96)="">

P(Z<= -1.28)="">
