11.67 What about garages?
CASE 11.3 We have not yet examined the number of garage spaces as a possible explanatory variable for price. Make a scatterplot of price versus garage spaces. Describe the pattern. Use a "smooth’’ fit if your software has this capability. Otherwise, find the mean price for each possible value of Garage, plot the means on your scatterplot, and connect the means with lines. Is the relationship approximately linear?
11.67
Other than the 1 house with 3 garage spaces, the plot is quite linear between 0 and 2 spaces.
