1. The unit improvement factor for a 60 percent learning curve at 25 units is 0.0933. The first and second timings of a person doing a job are 5 minutes and 3 minutes respectively. What is the learning-adjusted time estimate for unit number 25?

2. You have just timed a person doing a job a few times. The first time it took the person 25 minutes, the second time it took 20 minutes, and the third time it took 17.55 minutes. What learning curve unit improvement factor should you use?

3. You have determined that a 75 percent learning curve is appropriate for a task. If the initial timing of the person performing that job was 50 minutes, and if you need the job performed 500 times, how many minutes of work will be required?

4. With an 80 percent unit improvement factor learning curve and an initial time of 100 minutes to do a job, at what number of repetitions will the job take less than 50 minutes?

5. The 50th repetition of a job is timed at 100 minutes. If the learning curve for this job is 90 percent, what is the estimated time for the 100th repetition of this job?
