The appraisal of a warehouse can appear straightforward compared to other appraisal assignments. A warehouse appraisal involves comparing a building that is primarily an open shell to other such buildings. However, there are still a number of warehouse attributes that are plausibly related to appraised value. Consider the accompanying data on truss height (ft), which determines how high stored goods can be stacked, and sale price ($) per square foot. 15 15 16 Height 12 14 14 22 Price 35.54 37.83 36.90 40.02 38.00 37.52 41.02 48.49 18 22 24 47.02 47.50 Height 24 26 26 27 28 30 30 33 36 Price 46.21 50.34 49.15 48.05 50.88 54.80 54.32 57.18 57.45 (a) Estimate the true average change in sale price associated with a one-foot increase in truss height, and do so in a way that conveys information about the precision of estimation. (Use a 95% CI. Round your answers $0.888 $ 1.086 ]) three decimal places.) (b) Estimate the true average sale price for all warehouses having a truss height of 25 ft, and do so in a way that conveys information about the precision of estimation. (Use a 95% CI. Round your answers to three decimal places.) dollars per square foot (c) Predict the sale price for a single warehouse whose truss height is 25 ft, and do so in a way that conveys information about the precision of prediction. (Use a 95% PI. Round your answers to three decimal places.) ) dollars per square foot
