## Elementary Statistics (12th Edition)

The regression equation is the second line of the output: LDL=47.4+0.085WT+0.495SYS. WT=59.3, SYS=122, hence $LDL=47.4+0.085\cdot59.3+0.495 \cdot 122=112.8305.$ In exercise 7 we said that the regression equation should not be used for prediction, hence it is not likely to be a good prediction.
