A job with a 70 percent learning curve required 20 hours for the initial unit. The fourth unit should require approximately how many hours?

Suppose the first unit of output required 800 labor hours, and the second required only 640. How many hours will be reduced from the second unit to the fourth?

A company is preparing a bid on a government contract for 40 units of a certain product. The operations manager estimates the assembly time required for the first two units to be 10.4 hours and 8.8 hours. Approximately how long will it take to produce the 25^th through 30^th units?

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

The fact that human activities typically improve when they are done on a repetitive basis is described by a(n) :

According to learning curve theory, for certain kinds of tasks the cost per unit decreases as the number of repetitions increases.

A learning curve for an overqualified worker is higher than that for an average worker.

A company is preparing a bid on a government contract for 40 units of a certain product. The operations manager estimates the assembly time required for the first two units to be 10.4 hours and 8.8 hours. What is the expected time required to produce the 40^th unit?

A company is preparing a bid on a government contract for 40 units of a certain product. The operations manager estimates the assembly time required for the first two units to be 10.4 hours and 8.8 hours. Which unit, if any, will require approximately one-half the time of the first unit?

A job has an 80 percent learning curve. If the first unit took 40 hours to complete, the fourth unit should take roughly how many hours?

A job will have a learning rate of 75 percent. If the third unit requires 10 hours, the 12^th unit should require about this many hours:

Assembly of a model airplane has a learning curve of 80 percent. The estimated time to assemble a second identical model airplane is 40 hours. Determine approximately how much time will be required for: (A) the eighth unit. (B) the first 10 units.

The learning curve principle would apply to a baseball pitcher learning to throw a curveball.

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

The third unit of a 10-unit job required 7.3 hours to complete. The fourth unit has been worked on for two hours, but it is not yet finished. Estimate the remaining amount of time that will be needed to finish this 10-unit job if the work has an 80 percent learning curve.

According to learning curve theory, the time reduction per unit decreases (improves) as the number of units increases.

Increasing volumes result in ___________ the learning curve.

A job has a 70 percent learning curve. If the first unit took 10 hours to complete, the third unit should take roughly how many hours?
