Question: the cycle time in seconds for a worker to operate...

Question details

The cycle time (in seconds) for a worker to operate a process was measured 10 times with the following results: 8.2, 7.8, 9.5, 8.3, 7.7, 8.0, 7.9, 8.1, 9.2, 8.8. A work measurement analyst determined that the standard time should be calculated using a 90% rating factor to compensate for the typical worker who would operate the process, and a 15% allowance for external effects on the process. What is the resulting standard time for the process? POSSIBLE ANSWERS 6.39 seconds 7.81 seconds С 8.64 seconds 10.56 seconds
