A major car magazine has recently collected data on 30 leading cars in the U.S.market.It is interested in building a multiple regression model to explain the variation in highway miles.The following correlation matrix has been computed from the data collected: If only one independent variable (ignoring city mileage)is to be used in explaining the dependent variable in a regression model,the percentage of variation that will be explained will be nearly 74 percent.
