Suppose a manufacturer of copiers has concluded that a $70$ 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 six hours, what is an estimate of the time required by a new

technician to install the third and fourth copiers? Round your answers to one decimal place.

For $x=3$ it takes

hours

For $x=4$ it takes

hours

$10\mathrm{.}7$

b$.$ If the learning rate changes to $55$ or $90$ percent, what is an estimate of the time required by a new technician to install the third and

fourth copiers? Round your answers to one decimal place.

For $x=3$ and a $55\%LC,$ it takes

hours

For $x=4$ and a $55\%$ LC$,$ it takes

hours

For $x=3$ and a $90\%$ LC$,$ it takes

hours

For $x=4$ and a $90\%$ LC$,$ it takes

hours
