4. According to those who know, a sample of 360 one year old baby boys in the US had a mean weight of 26.5 pounds. Assume the population standard deviation is or 5.3 pounds. a. Construct a 95% confidence interval for the mean weight of all one-year old baby boys in the M = 262 = 5 M- 0.14 Y b. Based on the confidence interval level above, is it likely that the mean weight of one-year old boys is less than 28 pounds? M = 0.14 = 360 m= DAS X
