1. Given the above data, calculate the average labour per unit given the cumulative total labour hours provided. This model is based on the equation y = aXb where y= time to produce the last unit of output, a= time to produce the first unit, and b= the rate of learning. The rate of learning is calculated by taking the natural log of the percentage of learning and dividing by natural log of 2. Ultimately what this equation is describing, is that the incremental unit time decreases at a constant rate each time the quantity of units produced doubles.
