The births data set is part of the openintro package. It consists of random sample of 100 births for babies in North Carolina where the mother was not a smoker and another 50 where the mother was a smoker. A plot that shows the relationship between birth weight (weight) and mother's smoking status (smoke) is showing in the graph.

keep in mind that the person you are talking to has not taken Stas, therefore they will not be as familiar with the statistical vocabulary as you are. Therefore, make sure the explain any terms you use in plain language.
