In a multiple regression with three explanatory variables and 100 observations, it is found that SSR = 4.85 and SST = 8.66. a. Calculate the standard error of the estimate s. (Round intermediate calculations to at least 4 decimal places and final answer to 2 decimal places.) Standard error b. Calculate the coefficient of determination 2. (Round your answer to 4 decimal places.) Coefficient of Determination c. Calculate adjusted coefficient of determination 2. (Round your answer to 4 decimal places.) Adjusted Coefficient of Determination
