Build a linear regression model with ARR_DELAY column as the dependent variable and all other variables except ARR_DEL15 as explanatory variables. Note that you need to transform the categorical variables ORIGIN and DEST before building the model. You also should not include all dummy variables you created. Exclude the dummy variables ORIGIN_SFO and DEST_SFO in your analysis. What is the coefficient of DISTANCE
