Consider babies born in the "normal range" of 37-43 weeks gestational age. Extensive data supports the assumption that for such babies born in the United States, birth weight is normally distributed with miu=3432g and Sigma=482g. Once this data was converted to grams, the histogram showed normality.
- For babies of this type, what proportion of all birth weights exceeds 4000g?
- For babies of this type, what proportion of all birth weights is between 3000 and 4000g?
- How would you characterize the highest 0.1% of all birth weights?
- What value c is such that the interval (3432-c, 3432+c) includes 98% of all birth weights?
