The weight of chicken follows a normal distribution, with a mean of 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 u? Note that from the 2-distribution table, we know: P(Z<= -1.645) = 5% P(Z<= -1.96) = 2.5% P(Z<= -1.28) = 10% [5.347,6.653] O [5.787,6.213] O [5.673,6.327) (5.726,6.274) O None of the other answers
