| A job was timed for 60 cycles and had an average of 1.9 minutes per piece. The performance rating was 90 percent, and workday allowances are 18 percent. Determine each of the following: |
| a. | Observed time. (Round your answer to 1 decimal place.) |
| Observed time | minutes |
| b. | Normal time. (Round your answer to 2 decimal places.) |
| Normal time | minutes |
| c. | Standard time. (Round your answer to 2 decimal places.) |
| Standard time | minutes |
Homework Answers
A. Observed time(OT) = Average time = 1.9 minutes
B. Normal time = OT X performance rating = 1.9 * 0.9 = 1.71 minutes
C. Standard Time = ST = NT X AF
AF = Allowance factor = 1 / (1 - allowance) = 1 / (1 - 0.18) = 1.22
ST = 1.71 * 1.22 = 2.0862 minutes
Do give a positive rating if you think this answer helped

How many work cycles should be timed to estimate the average cycle time to within 2 percent of the sample mean with a confidence of 98.0 percent if a pilot study yielded these times (minutes): 4.1,4.6,5.1, 4.9, 5.9, and 4.4? The standard deviation is .631 minutes per cycle. (Use the "mean time" value to 2 decimal places and other values to 3 decimal places for intermediate calculations. Round up your final answer to the next whole number.) Number of work...

A worker-machine operation was found to involve 3.6 minutes of machine time per cycle in the course of 40 cycles of stopwatch study. The worker’s time averaged 2.1 minutes per cycle, and the worker was given a rating of 111 percent (machine rating is 100 percent). Midway through the study, the worker took a 10-minute rest break. Assuming an allowance factor of 11 percent of work time which is applied only to the worker element (not the machine element), determine...
