Bas ed only on this information, what would be the es timate of the learning perc entage in this proc es s ?
(Round your answer to 1 decim al place.) Es timated learning perc entage 80.0 ± 0.1 % Explanation: Learning c urv e theory s tates that as output doubles , the time to perform a tas k dec reas es by a fix ed
amount. In this problem, as we produc ed the s ec ond unit, we had doubled output from the firs t unit, s o we

a. You c an es timate the learning perc entage by av eraging the learning between the firs t and s ec ond units , the
s ec ond and fourth units , and the fourth and eighth units .
In this c as e that would be: (580/860 + 410/580 + 300/410)/3 = 70% . b. You c an figure this out by us ing the c umulativ e fac tors in Ex hibit 6.5. You want to find the time needed for
the 11th through 200th units . That is equal to the time for all 200 units minus the time for the firs t 10. So
tak e the c umulativ e fac tor for 200 units , s ubtrac t off the c umulativ e fac tor for 10 units , and multiply the
res ult by the firs t unit’s produc tion time. c.
