Increasing volumes result in _____ the learning curve.

The owner of Touchdown Sports Bar wants to develop a time standard for the task of mixing a specialty cocktail. In a preliminary study, he observed one of his bartenders perform this task seven times with an average of 90 seconds and a standard deviation of 5 seconds. How many observations should be made if he wants to be 95.44 percent confident that the maximum error in the observed time is 1 second?

One potential disadvantage of self-directed teams is higher turnover and absenteeism.

A learning percentage of 95 percent indicates greater learning than a percentage of 90 percent.

A methods and measurements analyst needs to develop a time standard for a certain task. In a preliminary study, he observed one of his workers perform this task five times, with the following results: 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 2 seconds? Assume that the standard deviation of the task time is 4 seconds.

Specialization is one of the sources of disagreement between the efficiency and behavioral approaches to job design.

According to learning curve theory, every doubling of total output will produce a constant percentage decrease in time per unit .

A methods and measurements analyst needs to develop a time standard for a certain task. In a preliminary study, he observed one of his workers perform this task five times, with the following results: What is the standard time for this task if the employee worked at a 25 percent faster pace than average and an allowance of 20 percent of the workday is used?

Predetermined time standards involve the use of published data regarding how long various activities are expected to take.

A manager wants to analyze the learning curve associated with producing one of his company's products. Accordingly, he has gathered the following data: What is the learning curve percentage?

The efficiency approach is a refinement of this person's scientific management concepts?

A methods and measurements analyst needs to develop a time standard for a certain task. In a preliminary study, he observed one of his workers perform this task five times, with the following results: What is the observed time for this task?

Work sampling can be used to estimate the proportion of time a machine is idle.

A methods and measurements analyst for Digital Devices needs to develop a time standard for the task of assembling a computer mouse. In a preliminary study, she observed one of her workers perform this task six times with the following results: What is the standard time for this task if the employee worked at a 20 percent faster pace than average and an allowance of 25 percent of the workday is used?

Work sampling provides a detailed elemental breakdown of a task for purposes of establishing reliable time standards.

The manager of Lawn and Garden Services would like to estimate the proportion of her employees' time spent performing various gardening and lawn care activities. She has made 400 random observations of a typical worker, with the following results: If the manager wants to be 95.44 percent confident that the true proportion of time spent mowing is within 0.02 (plus or minus) of the sample proportion, what should be her sample size?

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

Job enrichment involves an increase in the level of responsibility for planning and coordinating tasks.
