A new-age, urban farmer has been experimenting with a new diet for her chickens. Data below describe the weight in kg from a sample of chickens from the current flock. 1. 6.57, 6.67, 6.98, 6.17, 6.17, 6.93, 6.73, 6.87, 6.76, 6.06, 6.16 a. Do these data appear to be consistent with a normal distribution? b. Assuming α = 0.05, is there sufficient evidence to reject the null hypothesis that μ = 6.50 kg? c. What is the P-value for this test? d. In the previous test, what sample size would be required to detect a true mean 6.25 kg with probability 95%? For the test conducted in part a, what would be the type Il error probability if the true mean - 6.95 kg? e.
