(A) Estimate Sally's learning percentage:

(B) Using your answer from part A, estimate how long it will take Sally to finish the three remaining problems. Explain and show your answer.

Expert Solution

Step 1 (a)

As per the learning curve (moderate) :

(a) Sally's improvement from the first to the fifth unit is 17/33 = 0.515.

Since this value is close to = the entry 0.596 for the fifth unit under the 80% learning rate column of Table E.3. Therefore the learning rate is 80%.
