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. Estimate the probability that a random chosen baby has a weight between 3.4 and 10.6 pounds.
