Birth Weights Birth weights in Norway are normally distributed with a mean of 3570 g and a standard deviation of 500 g.
a. If the Ulleval University Hospital in Oslo requires special treatment for newborn babies weighing less than 2700 g, what is the percentage of newborn babies requiring special treatment?
b. If the Ulleval University Hospital officials plan to require special treatment for the lightest 3% of newborn babies, what birth weight separates those requiring special treatment from those who do not?
c. Why is it not practical for the hospital to simply state that babies require special treatment if they are in the bottom 3% of birth weights?
