R square is considered as measurement of goodness of fit in the data. Thus 47.46% of the variation in van operating costs can be explained by variation in miles driven. This is considered as a weak model because more than 50% variation in the van operating costs cannot be explained by variation in the miles drive. Hence the company should not rely on this estimate. + X 16500 0.1914 0.19135833 3158.1 5321.91 2163.81 2163.804771 2163.81
