Question

Quizplus · Accepted Answer

The learning curve formula is Tn = T1 * n^b, where Tn is the time required for the nth unit, T1 is the time required for the first unit, n is the unit number, and b is the learning curve coefficient. For a 70 percent learning curve, b = log(0.7) / log(2). Therefore, the time for the fourth unit (n=4) can be calculated, which approximately equals 9.8 hours.
