The calculation of the coefficient of determination r2 depends on the number of independent variables. An adjusted value of r2 based on the number of degrees of freedom is calculated using the formula shown below, where n is the number of data pairs and It. is the number of independent variables. 2 1_[[1F]m1{ av: nk1 Data were found on eight pre-owned sedans of a certain make. Suppose a multiple regression on these data has 4 independent variables. The coefcient of deten'nination is found to be 0.964 based on a sample of 24 paired observations.After calculating r2 j , determine the percentage of the variation in y that can be explained by the relationships between variables according to rid,\" Compare this result with the one obtained using r2. ridj=l:| {Round to three decimal places as needed.) About Dbl: of the variation in y can be explained by the relationships between variables. {Round to one decimal place as needed} The value of rid] is E the value of r2
