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

Experienced methods analysts generate improvement ideas for the job by asking all of the following questions EXCEPT:

An advantage of work sampling,compared to a stopwatch time study is that,the observations can be spread out over a period of time in work sampling.

Task specialization is one of the three categories of motion economy principles.

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

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

-If the person observed worked at a pace that is 20 percent faster than average,and if the appropriate allowance for this task is 25 percent of the workday,what should be the standard time?

Potential benefits of "self-directed teams" include higher productivity and greater worker satisfaction.

Ergonomics is important for preventing common workplace injuries such as back injuries and repetitive motion injuries.

In a stopwatch time study,adjusting the observed time by the performance rating of the observed worker results in the:

Work sampling involves the use of some method of randomizing the observations.

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

Efficiency generally declines after a work break.

Job enrichment involves giving a worker a greater share of the total task,which is sometimes referred to as horizontal loading.

A performance rating of less than 1.00 means that the observed worker was judged to be working faster than the normal rate.

The standard time for a job can be obtained by multiplying the normal time by an appropriate allowance factor.

The normal time for a job is multiplied by the performance rating to obtain the standard time for the job.

Given the following work sampling data, based upon 100 random observations of a particular worker: -For a confidence level of 95.44% and a maximum error of.04,what should be the sample size for estimating the proportion of time spent performing activity A? B? C?
