Selling apartment buildings. Continue with the data from the previous exercise. Create a new variable (call it Sale Price Per Sqft) by dividing the selling price for each apartment building by the square footage for each apartment building.

(a) When plotting selling prices or building square footages, one apartment building stands out as an outlier. Does this same apartment building stand out in terms of the new variable you created for this exercise? Explain your response clearly.

(b) Use statistical software to obtain a histogram and a Normal quantile plot of the new variable Sale Price Per Sqft.

(c) Does the distribution of Sale Price Per Sqft appear to be Normal? Describe precisely what about the histogram and the Normal quantile plot leads you to your conclusion.
