Breastfeeding burns up to 500 calories per day, so does that mean that women who breastfeed their infants will lose more weight than women who formula feed their infants? A group of researchers studied the amount of weight lost after giving birth by mothers who breastfed their infants and mothers who chose formula feeding. They randomly chose 29 breastfeeding mothers and 21 formula feeding mothers. The researchers recorded how much weight each group lost at 12 months after childbirth. The amount of weight lost was found to be normally distributed. The difference in the mean amount of weight lost for the two samples (breastfeeding vs. formula feeding) is 2.0 kg and the 95% confidence interval is (1.05, 4.19).Which statement gives the best interpretation of what we can conclude about the impact of breastfeeding on the amount of weight lost after childbirth? This study does not suggest that there is a difference in mean amount of weight lost after childbirth when we compare breastfeeding mothers to formula feeding mothers. When breastfeeding mothers are compared to formula feeding mothers, we are 95% confident that the mean amount of weight lost 12 months after childbirth is between 1.05 kg and 4.19kg more than the mean amount of weight lost by formula feeding mothers. We are 95% confident that on average, breastfeeding causes an extra weight loss of 1.05 kg to 4.19 kg. There is a 95% chance that if a woman breastfeeds her baby that she will lose an extra 1.05 kg to 4.19 kg than if she used formula to feed her baby.

1) Discuss why some women choose to breastfeed their infants?

Modern medical practice tells us not to encourage babies to become too fat. Is there a positive correlation between the weight x of a 1-year-old baby and the weight y of the mature adult (30 years old)? A random sample of medical files produced the following information for 14 females: x (lb) 21 25 23 24 20 15 25 21 17 24 26 22 18 19 y (lb) 125 125 120 125 130 120 145 130 130 130 130 140 110 115 a.
