Answer:
a) 86%
b) 2nd unit = 82 hs.
3rd unit = 75 hs
c) 100th unit = 36 hs
Step-by-step explanation:
We can model the learning curve for manufacturing the units as:
where t is the time for the Xth unit, and a and b are parameters that we will calculate from the data,
We know that t(1)=95. Then, we have:
And we know that the fourth unit (X=4) take 71 hours to be completed (t(4)=71). Then, we can calculate the other parameter as:
We have the model for the learning curve:
The learning rate percentage is calculated from the b parameter:
The learning rate percentage is 86%.
b) The most likely times required for the 2nd and 3rd units are calculated with the model:
c) If we use the model to calculate the time required for the 100th unit, we have:
