If the learning factor improved to 70%, 1) How would the cost change? It would drop to $__________________________ 2) What would be the total cost to make all four boats? $___________________________________________ 2. (5 points) Briefly explain the concept of the doubling effect in learning curves. 3. (15 points) Providence Assessment Center screens and trains employees for a computer assembly firm in Boston. The progress of all trainees is tracked, and those not showing the proper progress are moved to less demanding programs. By the tenth repetition, trainees must be able to complete the assembly task in 1 hour or less.

Should you encourage either or both of the trainees to continue? Why? [Hint: For each trainee, 1) Determine the learning rate (%) use doubling concept. 2) Calculate time for the 1st unit (T1) use table, 3) Calculate time for the 10th Unit (T10) use table]
