nit test Previous question 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 k is the number of independent variables. 2 - [(1-12) (1 - 1) ] n- k - 1 Data were found on eight pre-owned sedans of a certain make. Suppose a multiple regression on these data has 7 independent variables. The coefficient of determination is found to be 0.997 based on a sample of 20 paired observations. After calculating a; , determine the percentage of the variation in y that can be explained by the relationships between variables according to ;. Compare this result with the one obtained using r2. . . . adj (Round to three decimal places as needed.) About % of the variation in y can be explained by the relationships between variables. (Round to one decimal place as needed.) The value of radi is equal to the value of 2
