The management of Brinkley Corporation is interested in using simulation to estimate the profit per unit for a new product. The selling price for the product will be $45 per unit. Probability distributions for the purchase cost, the labor cost, and the transportation cost are estimated as follows: Procurement Labor Cost ($) Probability Cost ($) Probability Transportation Cost ($) Probability 10 0.25 20 0.10 3 0.75 11 0.45 22 0.25 5 0.25 12 0.30 24 0.35 25 0.30 (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: $ 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 proportion? Round your answers to one decimal of a percentage. Lower Bound: % Upper Bound: %
