4. (7 points) Given the lot data shown in table 1 complete table 2 and determine the unit theory learning curve. Assume an 85% learning curve to begin the analytical process. Table 1 Lot Number Units in Lots Cost (Man Hours) + 1 20 3000 2 50 5500 3 25 2500 Table 2 Units Cost Lot in Number (Man First Last LMP AUC Ln(LMP) Ln(AUC) Lots Hours) 1 20 3000 2 50 5500 I 3 25 2500 a. Develop the learning curve equation. b. Assume that the next lot, lot 4, contains 20 units. Estimate the cost in man hours for that lot.
