11.118 Energy efficiency of buildings. Firms conscious of the energy efficiency of proposed new structures are interested in the relation between yearly energy consumption and the num- ber of square feet of building shell. The table (next page) lists the energy consumption in British thermal units (a BTU is the amount of heat required to raise 1 pound of wa- ter 1°F) for 22 buildings that were all subjected to the same climatic conditions. Consider a straight-line model relating BTU consumption, y, to building shell area, x. a. Find the least squares estimates of the intercept B and the slope B. b. Investigate the usefulness of the model you developed in part a. Is yearly energy consumption positively lin- early related to the shell area of the building? Test using a- .10. e. Find the observed significance level of the test of part b. Interpret its value. BTU
