for true concentration of the sample. Newborn weight. The 95% confidence interval for the mean weight of infants 1012 born to mothers who smoke is 5.7 to 6.5 pounds. The mean weight for all newborns in this region is 7.2 pounds. Is the birth weight of the infants in this sample significantly different from that of the general population at α = 0.05? Explain your response.
