Load the Boston housing data (Boston) from the package MASS. This data contain housing values and hedonic characteristics for 506 areas in the Boston suburbs. We're going to try to predict median value of homes (medv) as a function of neighborhood characteristics. First, summarize the dataset, and use ggpairs or other visualization tools to familiarize yourself with the data. Next regress median housing values against crime rate, average number of rooms per dwelling, age, distance to downtown, and pupil-teacher ratio. Interpret each coefficient in your own words
