Using R, consider the Carseats dataset from the ISLR library. Split the dataset into two portions, a random 60% will be the training dataset, and the remaining 40% will be the testing data. Use tree() to fit a regression tree to the training set, the response variable will be Sales. Plot the tree, and interpret the results. What test MSE do you obtain?

A real estate analyst believes that the three main factors that influence an apartment's rent in a college town are the number of bedrooms, the number of bathrooms, and the apartment's square footage. For 40 apartments, she collects data on the rent (y, in $), the number of bedrooms (x1), the number of bathrooms (x2), and its square footage (X3). The following table shows a portion of the regression results.

One Step Fitness, a local gym, is interested in growing its membership. They have hired an ad agency who recommended that they do direct mail to local residents. After mailing repeatedly for 19 weeks, the company wants to figure out if more mail results in more sales. Below is a scatterplot showing how many direct mail pieces were sent out each week and what the sales of gym memberships were for that week, over the course of the 19 weeks of the campaign. The regression line for this scatterplot is shown. The equation of the line is below, as is r-squared. S a l e s = 33.300517 + 0.0224187 ⋅ D i r e c t M a i lS a l e s = 33.300517 + 0.0224187 ⋅ D i r e c t M a i l R 2 = 0.063413R 2 = 0.063413 What do the coordinates of a dot on the scatterplot represent?
