If the residual error is 35 and the predicted cost value is 20, the observed cost value will be _________?
Show answer Hide answer
Answer: A. 55
Explanation
Adding the residual error to the predicted cost value determines the observed cost value. Summing twenty for the predicted cost and thirty-five for the residual error gives the total. This addition correctly results in an observed cost value of fifty-five total units. Residual errors represent the difference between statistically predicted costs and actual observed data. Predicted cost values are estimated using regression models based on historical trends. Observed cost values reflect actual historical figures recorded during operations.
Cost analysts use regression techniques and residual analysis to forecast future expenses. Evaluating prediction accuracy helps organizations refine their budgeting models for better results. Accurate cost observation ensures reliable financial reporting and effective management decisions. Alternative figures result from subtracting or incorrectly combining the statistical variables. Distractor options fail to represent the proper sum of the predicted cost and residual error. Choosing an incorrect option indicates unfamiliarity with standard regression calculation methods.
