An estimated regression for a random sample of observations on an assembly line is Defects: 2.8 + 0.044 Speed, where Defects is the number of defects per million parts and Speedis the number of units produced per hour. The estimated standard error is 59 : 1.23. Suppose that 75 units per hour are produced and the actual (observed) defect rate is Defects = 5.3. (a) Calculate the predicted Defects. (Round your answer to 2 decimal places.) Predicted Defects [ lper million parts (b) Calculate the residual. (Negative value should be indicated by a minus sign. Round your answer to 2 decimal places.) RBSIdual e1; [ (c) Calculate the standardized residual using 59. (Negative value should be indicated by a minus sign. Round your answer to 3 decimal places.)
