رجم (Round to three decimal places as needed.) (Round to three decimal places as needed.) About % of the variation in y can be explained by the relationship between the variables. (Round to one decimal place as needed.) Compare rd and r². Choose the correct answer below. A. The value for is less than the value for r². B. The value for c. The value for r 'adj adj is greater than the value for r². is the same as the value for r². 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 adj =1- (1-2) (n-1) n-k-1 Data were found on eight pre-owned sedans of a certain make. Suppose a multiple regression on these data has 6 independent variables. The coefficient of determination is found to be 0.901 based on a sample of 18 paired 2 adj, observations. After calculating r determine the percentage of the variation in y that can be explained by the relationships between variables according to r2d. Compare this result with the one obtained using r². adj
