Exam 10: Human Resources,job Design,and Work Measurement

How many observations would be necessary for a time studies analyst to be 99% confident that the average time is within ± .1 minutes of the true value,if the average time is 10.5 minutes and the standard deviation is 3 minutes?

Extended periods of exposure to decibel levels above ________ has been judged to be permanently damaging.

Identify the five steps of the work-sampling procedure.

The data below represent time study observations for an assembly operation.Assume a 7% allowance factor.What is the normal time for element 3?

Which of these is the most common predetermined time standard?

The preferred method of choice for setting labor standards is to base them on historical experience.

In a perfectly fitting chair,and you are a male in the 50th percentile,your chair should be:

A task involves positioning two metal parts with a rubber gasket sandwiched between them,inserting two bolts into predrilled holes,threading a nut onto each bolt,and tightening each bolt with a pneumatic wrench.In a preliminary study,the manager observed one of his workers performing this task five times.The observations were made in an air-conditioned,well-lit training facility,at ground level,with all tools and equipment clean and readily available. a.What is the average observed time for this task? b.What is the normal time for this task if the employee worked at a 10% slower pace than is typical for adequately trained workers? c.What is standard time for this task if allowances sum to 14%?

What is methods analysis?

The accuracy of a labor standard is to be within ± 5%,and the confidence level is 95%.The standard deviation of the sample is 2 and the mean is 8.What sample size should be used?

The phrase,"designed to show economy of motion by pointing out wasted motion and idle time (delay)," describes which of the following?

In a preliminary work sample of an operation,out of 50 observations the operator was observed idle in 5 observations.What sample size is required for a work sampling study if the desired confidence level is 99% and the desired accuracy level is ± 5%?

The average observed time for a given job is 10 minutes.The performance rating is 80%,and allowances are set by contract at 10%.What is the standard time?

It is said that job expansion has both a vertical component and a horizontal component.Explain,with reference to such terms as job enrichment,job rotation,and job enlargement.

The physical environment in which employees work may affect the quality of work life,but it does not affect their performance and safety.

A time measurement unit,or TMU,is:

________ is the grouping of a variety of tasks using the same approximate skill level.

An advantage of work sampling is that it completely breaks down work elements.

Working four shifts of ten hours each instead of five shifts of eight hours each is known as which of the following?

Which of the following is not a method used to set labor standards?
