2. Compute the regression statistics and predictive function for this data;
4. Identify R square (R²) and the standard error of the estimate;
6. What is the estimated overhead if 1,000 units are produced?
8. What is the 95% prediction interval for the true overhead when the number of units produced is 1,000?
10. What is the "residual" for the fifth observation (round to two decimal places)?
