(a) Identify R square (R 2 ) and the standard error of the estimate; (b) What is the estimated overhead if 1,000 units are produced? (c) What is the 95% prediction interval for the true overhead when the number of units produced is 1,000? (d) What is the residual for the fifth observation (round to two decimal places)?
