Exam 7: Work Design and Measurement

What is the standard time (ST) for this task if the employee worked at a twenty-five percent faster pace than is average and an allowance of twenty percent of the workday is used?

A work sampling study is needed that will estimate the percentage of time a postal clerk spends selling stamps as opposed to other duties.Determine the necessary sample size to estimate that proportion with a confidence of 99.74 percent to within 3 percent, for these cases: 1) No information is currently available concerning that proportion. 2) The proportion is probably no more than 15 percent.

How many observations should be made if the analyst wants to be 99.74 percent confident that the maximum error in the observed time is two seconds? Assume that the standard deviation of each task time is 4 seconds.

What is the normal time (NT) for this task if the employee worked at a twenty-five percent faster pace than average?

What is the standard time (ST) for this task if the employee worked at a twenty-five percent faster pace than is average and an allowance of twenty percent of job time is used?

How many observations should be made if she wants to be 95.44 percent confident that the maximum error in the observed time is two seconds? Assume that the standard deviation of the task time is 6 seconds.

The methods analysis chart which describes the portions of a work cycle during which an operator and equipment are busy or idle is a:

No stopwatch is required in a work sampling study.

For a confidence level of 86.64%, what is the maximum error of the estimate for activity A?

Standard times derived from a firm's historical data are known as:

An analyst has observed 28 work cycles, for which the average cycle time was five minutes and the performance rating was 1.05.Allowances for the department are 25 percent of job time.What standard time is appropriate for this job?
