According to the National Health Statistics Reports, a sample of 360 one-year-old baby boys in the United States had a mean weight of 25.5 pounds. Assume the population standard deviation is σ = 5.3 pounds. Construct a 99% confidence interval for the mean weight of one-year-old baby boys in the United States. Based on this confidence interval, is it likely that the mean weight of all one-year-old boys is less than 28 pounds?
