abs 46551 p set 4 ### Problem 1 (9 points). The typical weight of a baby at birth for the US population is 3,250 grams. Suppose an investigator takes a random sample of 50 birth weights from several teaching hospitals located in an inner-city neighborhood. The birth weights are stored in the \texttt{birth.weights} data frame.

The results of this analysis will inform whether an educational program for pregnant women that promotes exercise and healthy eating should be started at the neighborhood community center
