12. A process has been studied and the following times have been collected. Number Made N Time to make in minutes 28 2 24 4 18 21 16 14 10 Using the doubles approach, determine the learning curve rate and calculate the projected time for the 10th unit. a. b. Using regressio n, determine the learning curve rate and calculate the time for the 10th unit.

Solution

The learning curve rate is 75.93

The projected time for the 10^th unit is

b.

Y=29.214-2.547x

=29.214-2.547*10 =3.744
