a)

Summary Introduction

To determine: The time required for the fourth and eighth installation for a learning rate of 92%.

Introduction:

Learning curve:

Learning curve is based on the premise that when a person is repeating a task or job again and again, the performance of the person on that job or task will improve. It will depict relationship between cost and output over a definitive period of time.

Doubling effect:

The concept is that each time when an output is doubled, the time it took to develop the doubled unit will be x% of the time it took to produce the base unit. Here ’x’ is the learning curve rate.

b)
