One factor in assessing the value of a warehouse is the height to which goods can be stacked. the data below are the recorded stacking heights and property values (per square foot) for a sample of 19 warehouses in the year 2001. you can use r for your calculations. height (ft) price ($/ft) 12 39 14 38 14 37 15 40 15 38 16 38 18 22 22 24 24 26 26 27 28 30 30 33 36 41 49 47 48 46 50 49 48 51 55 54 57 57 (e) estimate the average change in price per square foot associated with a one-foot increase in stackable height. (f) estimate the average price per square foot for the population of warehouses that have a stackable height of 25 feet. (g) predict the sale price for some single unobserved warehouse with stackable height of 25 feet, and report a 95% confidence interval.
