Suppose Charlene Brewster has times (in seconds) of 8.4, 8.6, 8.2, 8.6, 8.7, 8.5 and a performance rating of 90%. The normal time for this operation = seconds (round your response to two decimal places). Based on the normal time and the observed times, Charlene's work performance should be rated as

If Charlene Brewster has times of 8.4, 8.6, 8.3, 8.5, 8.7,and 8.5 and a performance rating of 110%, what is the normaltime for this operation? Is she faster or slower than normal?

A time study analyst timed an assembly operation for 30 cycles, and then computed the average time per cycle, which was 18.75 minutes. The analyst assigned a performance rating of .96, and decided that an appropriate allowance was 15 percent. Assume the allowance factor is based on the workday. Determine the following: the observed time (OT), the normal time (NT), and the standard time (ST).

Suppose Charlene Brewster has times ( in seconds) of 8.5,8.7,8.3,8.5,8.7,8.5 and a performance rating of 110%. the normal time for this operation =

Given below ratings based on skill and effort, compute for the average observed time if the normal time is 8 minutes? Skill – A1 +0.15; Effort – B1 +0.10

Jell Lee Beans is famous for its boxed candies, which are sold primarily to businesses. One operator had the following observed times for gift wrapping in minutes: 2.3, 2.7, 2.4, 2.4, 2.3. The operator has a performance rating of 110% and an allowance factor of 10%. The standard time for this gift-wrapping operation = minutes (round your response to one decimal place).

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?

An analyst has timed a metal cutting operation for 60 bikes. The average time per cycle was 10.30 minutes, and the standard deviation was 1:20 minutes for a worker with a performance rating of 120 percent. Assume an allowance of 16 percent of job time. Find the standard time for this operation.

The work cycle in a worker–machine system consists of (1) external manual work elements with a total normal time of 0.42 min, (2) a machine cycle with a machine time of 1.12 min, and (3) internal manual elements with a total normal time of 1.04 min. (a) Determine the standard time for the cycle, using a PFD allowance factor of 15% and a machine allowance factor of 30%. (b) How many work units are produced daily (8-hour shift) at standardperformance?

The 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 produced
