An analyst has timed a metal-cutting operation for 50 cycles. The average time per cycle was 8.9 minutes, and the standard deviation vas 1.09 minutes for a worker with a performance rating of 109 percent. Assume an allowance of 9 percent of job time. Find the standard time for this operation. (Do not round intermediate calculations. Round your final answer to 2 decimal places.) A job was timed for 60 cycles and had an average of 1.13 minutes per piece. The performance rating was 83 percent, and workday allowances are 8 percent. Determine each of the following: a. Observed time. (Round your answer to 2 decimal places.) b. Normal time. (Round your answer to 2 decimal places.) c. Standard time. (Round your answer to 2 decimal places.)
