1. The mean weight of all newborn babies in the US is 7 pounds with a standard deviation of 1.8 pounds. You
may assume that weights of newborn babies have a normal distribution. For this question draw a picture of
the model and label the standard deviation ruler.
(a) Estimate the probability that a randomly chosen baby has a weight between 3.4 and 10.6 pounds.
(b) Newborn babies who weigh too little at birth will need an incubator for some length of time. A hosp
iu
wants to make sure they have enough incubators to take care of the lightest 16% of babies. What weight
separates the bottom 16% from the rest?
