A recently negotiated union contract allows workers in a shipping department 24 minutes for rest, 10 minutes for personal time, and 14 minutes for delays for each four hours worked. A time study analyst observed a job that is performed continuously and found an average time of 6.0 minutes percycle for a worker she rated at 95 percent. What standard time is applicable for that operation?
The cycle time for performing a certain task has been clocked at 13 minutes. The performance rating of Richard Muszynski III was estimated at 120%. Common practice in this department is to allow 6 minutes of personal time and 4 minutes of fatigue time per hour. In addition, there should be an extra allowance of 3 minutes per hour for inspection. a) The normal time for the operation is = ? minutes (round your response to one decimal place).
Use excel to show formulas 2.A job had an observed time of five minutes, a performance rating of .70, and an allowance factor of 20 percent of job time. Twenty cycles were timed. Standard time for the job in minutes is:
Comment on the following: “At any given instant, the standard times for many jobs will not bestrictly correct.”a. Why is this so?
A worker-machine operation was found to involve 3.3 minutes of machine time per cycle in the course of 40 cycles of stopwatch study. The worker’s time averaged 1.9 minutes per cycle, and the worker was given a rating of 120 percent (machine rating is 100 percent). Midway through the study, the worker took a 10-minute rest break. Assuming an allowance factor of 12 percent of work time, determine the standard time for this job.
A job was timed for 60 cycles and had an average of 1.2 minutes per piece. The performance rating was 95 percent, and workday allowances are 10 percent. Determine each of the following:a. Observed timeb. Normal timec. Standard time
A time study of an employee assembling peanut valves resulted in the following set of observations. What is the standard time, given a performance rating of 97 percent and an allowance of 10 percent of the total normal time? LOADING...

The “worker” in this scenario had to perform a candy-sorting task and the rest of the class had to record the observed times (OT) for the task. It was decided that the rating for the “worker” was 100%. Given the following table, find the standard time for each element. Write your answers in order from Element #1 --> Element #5. Answers must have one decimal place: e.g. 3.0 or 12.5. Round up if necessary. Assume a total allowance of 5%. In your equation you will use for ST, consider allowance to be 0.05.
