How many independent variables are there? Independent variables c. How many dependent variables are there? Dependent variables d-1. Compute the standard error of estimate. (Round the final answer to 3 decimal places.) Standard error of estimate d-2. About 95% of the residuals will be between what two values? (Round the final answers to 3 decimal places. Negative answer should be indicated by a minus sign.) 95% of the residuals will be between and e-1. Determine the coefficient of multiple determination. (Round the final answer to 3 decimal places.) Coefficient of multiple determination value is
