Question

Question 3 2 pts The first unit of a product took 80 days for production. The learning rate for the production process is 85%. How long will it take to make the units 10th through 13th? (Use Table E.3 in Module E (Learning Curves) of the textbook.) from 115 to 135 days from 175 to 195 days from 135 to 155 days from 155 to 175 days from 195 to 215 days

Answer 1

The time taken to produce the first unit = 80 days

Learning rate = 85%

The cumulative improvement factor for 13 units at 85% learning rate = 8.792

The cumulative improvement factor for 9 units at 85% learning rate = 6.533

The total time taken to produce units 10^th through 13^th = (The cumulative improvement factor for 13 units at 85% learning rate - The cumulative improvement factor for 9 units at 85% learning rate) * The time taken to produce the first unit

= (8.792 - 6.533) * 80

= 180.72 days

Hence the correct answer is option B, i.e. from 175 to 195 days
