A statistical program is recommended. Consider the following data for two variables, x and y. 4 5 8 7 16 (a) Compute the standardized residuals for these data. (Round your answers to two decimal places.) X; Y₁ Standardized Residuals 10 17 X; 12 20 X; 12 24 4 22 18 5 Y; 13 14 16 16 13 7 14 8 10 16 12 22 Do the data include any outliers? Explain. O There is at least one standardized residual that are less than -2 or greater than +2, so there is a possible outliers. O There are no standardized residuals that are less than -2 or greater than +2, so there are no possible outliers. (b) Compute the leverage values for these data.
