3: Boston Data Set Analysis 1. For each predictor, fit a simple linear regression model to predict the response. Describe your results. In which of the models is there a statistically significant association between the predictor and the response? Create some plots to back up your assertions. 2. Fit a multiple regression model to predict the response using all of the predictors. Describe your results. For which predictors can we reject the null hypothesis H0 : j = 0? 3. How do your results from 3.1 compare to your results from 3.2? Create a plot displaying the univariate regression coefficients from 3.1 on the x-axis, and the multiple regression coefficients from 3.2 on the y-axis. Each predictor is displayed as a single point in the plot, with its coefficient in a simple linear regression model on the x-axis and its coefficient estimate in the multiple linear regression model on the y-axis
