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. What is the normal time for this task if the bartender worked at a 20 percent faster pace than is average?

What is the effect of an increase in the desired confidence level on the number of observations necessary in a time study?

Therbligs are basic elemental motions.

A job has an 80 percent learning curve. If the first unit took 50 hours to complete, the third unit should take roughly how many hours?

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: How many observations should be made if she wants to be 86.64 percent confident that the maximum error in the observed time is 0.5 second? Assume that the standard deviation of the task time is 4 seconds.

A manager is trying to estimate the learning rate for a new job. The first unit took 16 hours and the fourth unit required about 13 hours. The learning rate is:

A standard time is the amount of time it should take a fully trained and qualified worker to complete a specific task, working at an efficient, yet sustainable pace, using their choice of methods, tools, equipment, and workplace arrangement.

One disadvantage of specialization is worker dissatisfaction.

The learning curve principle would apply to the number of students in a class: a class twice as large will learn 80 percent faster.

Which of the following concerns is not one that job designers focus on?

Which of the following is not a potential benefit of the use of self-directed teams?

The decrease in time between the second and fourth units will be equal to the decrease in time between the first and second units.

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

A flow process chart is helpful for visualizing the portions of a work cycle during which the equipment is busy or idle.

Which of the following is not generally considered an advantage of specialization?

A methods and measurement analyst wants to develop a time standard for a certain task. In a preliminary study, he observed one worker perform the task six times with an average observed time of 20 seconds and a standard deviation of 2 seconds. What is the normal time for this task if the employee worked at a 20 percent faster pace than average?

A disadvantage of teams is:

The more _____ a task, the less likely it is that a substantial learning curve will be in effect.
