Suppose a manufacturer of copiers has concluded that a 65 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 five hours, what is an estimate of the time required by a new technician to install the fourth and fifth copiers? Round your answers to one decimal place. For x = 4 it takes hours For x = 5 it takes b. If the learning rate changes to 60 or 90 percent, what is an estimate of the time required by a new technician to install the fourth and fifth copiers? Round your answers to one decimal place. For x = 4 and a 60% LC, it takes For x = 5 and a 60% LC, it takes For x = 4 and a 90% LC, it takes For x = 5 and a 90% LC, it takes hours hours hours hours hours
