- 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% (machine rating is 100%). Midway through the study, the worker took a 10-minute rest break. Assuming an allowance factor of 12% of work time, determine the standard time for this job. Hints: you should consider both machine time and machine time together. Also, Allowance only applies to the man, not a machine.arrow_forwardThe owner of Kat Motel wants to develop a time standard for the task of cleaning a cat cage.

- Based on a careful work study in the Hofstetter Corp., the results shown in the following table have been observed: a) Compute the normal time for each work element.b) If the allowance for this type of work is 15%, what is the standard time?c) How many observations are needed for a 95% confidence level within ±5% accuracy? (Hint: Calculate the sample size of each element.)arrow_forwardThe snapback timing method was used to obtain the average times and performance ratings for work elements in a manual repetitive task. (See table below). All elements are worker-controlled and were performance rated at 80%. Element e is an irregular element performed every five cycles. A 15% allowance for personal time, fatigue, and delays isapplied to the cycle. Determine (a) the normal time and (b) the standard time for this cycle. If the worker’s performance during actual production is 120% on all manual elements for 7 actual hours worked on an 8-hour shift, (c) how many units will be producedarrow_forwardHow would you classify the following job elements?
