Probability distributions for the urchase cost, the labor cost, and the transportation cost are estimated as follows: (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
