Consider the attached medical cost personal data set, pre-process the data set,and applymultiple regression to forecast future medical costs. Build the regression model, explain how it works, and analyze your model with respect to F-score and P values showing the significance of the model with respect to the null hypothesis. In the .doc file add screenshots for a couple of testing examples to show how your model works on newly unseen data. Finally, submit your code file from Jupyter Notebook.
