Suppose a manufacturer of copiers has concluded that a 75 percent learning curve applies to the time a beginning service technician takes to install copy machines. Use the Learning Curve Excel template to answer the following questions:

a. If the time required to install the first copy machine is estimated to be four hours, what is an estimate of the time required by a new technician to install the second and third copiers?

b. If the learning rate changes to 60 or 95 percent, what is an estimate of the time required by a new technician to install the second and third copiers?
