using simulatio to estimate the profit per unit for a new product. The selling price for the product will be $45 per unit. Probability distributions for the purchase cost, the labor cost, and the transportation cost are estimated as follows: Procurement Cost ($) 10. 11 12 Labor Probability Cost ($) Probability 0.25 0.45 0.30 20 7.27 22 24 25 0.10 0.25 0.35 0.30 Transportation Cost ($) 3 5 Probability 0.75 0.25 (a) Construct a simulation model to estimate the average profit per unit. What is a 95% confidence interval around this average? Round your answers to two decimal places. Lower Bound: $ 7.03 Upper Bound: $ (b) Management believes that the project may not be sustainable if the profit per unit is less than $5. Use simulation to estimate the probability that the profit per unit will be less than $5. What is a 95% confidence interval around this prenestiae?
