An estimated regression for a random sample of observations on an assembily line is Defects = 3.3 + 0.046 Speed, where Defects is the number of defects per million parts and Speed is the number of units produced per hour. The estimated standard erroris s, = 1.20. Suppose that 100 units per hour are produced and the actual (observed) defect rate is Defects = 4.0. (a) Calculate the predicted Defects. (Round your answer to 2 decimal places.) Predicted Defects | | per million parts (b) Calculate the residual. (Negative value should be indicated by a minus sign. Round your answer to 2 decimal places.) Residual e; [ | (c) Calculate the standardized residual using s.. (Negative value should be indicated by a minus sign. Round your answer to 3 decimal places.) Standardized residual e;* _ (d) Is this observation an outlier? O Yes O No
