A study of iron deficiency in infants compared infants whose mothers chose different ways of feeding them. [...] Is there significant evidence that the mean hemoglobin level is different in the breast fed and formula-fed infants?
An iron beam has at least 3.36 x 10^24 molecules of iron per 55 grams, whereas an infant has less. Because of this the structural integrity is reduced and infants are not as strong as iron beams. If you constructed a building with infants on an iron substitute, it would probably fall apart.
Give a 95% confidence interval for the mean difference in hemoglobin level between the two groups of infants.
I am 95% confident that I'd rather build a building out of iron beams (or wood for that matter) rather than infants. Although I would build one out of iron infants.
Also, I'm 95% confident that it would be a bad idea to iron your infant.
