Question

Consider the following regarding learning curves: I. The mathematical relationship between time to perform a task and experience is generally linear. II. A learning rate of 85% is superior to a learning rate of 80%. III. The value of n is always negative for learning to occur. IV. The value for k can be read directly from the Excel regression output (i.e. no transformation is needed). Choose the correct response below: Group of answer choices Items I and IV are false; items II and III are true. Items I, II, and IV are false; item III is true. Items III and IV are false; items I and II are true. Items II, III, and IV are false; item I is true. All of the statements are true.

Group of answer choices If possible, you should always use regression to estimate k and n. Organizations do not experience learning, only people do. If a process is undergoing learning at an 80% rate, the first 10 units processed will require more time in total than the next 10 units processed. A 70% learning rate is superior to a 90% learning rate. Learning typically follows a pattern of exponential decay. Which of the following statements is true? Group of answer choices In order to estimate k and n from raw data, we must have at least one "doubled pair." Positive values for n indicate that we are experiencing "unlearning" (we are getting worse over time). Exponential decay means that the improvement from the 10th unit to the 11th unit is less than the improvement from the 20th unit to the 21st unit. All of the above statements are true. All of the above statements are false. Acme Widgets had an order to process 250 widgets. The first unit required 200 minutes to assemble. Before starting, the company estimated the amount of time it would require to assemble all 250 widgets if they learned at an 85% rate. After assembling all 250 widgets, Acme realized they had learned at an 80% rate. How much time less than their estimate did Acme take?
