Question 17 5 pts As part of the work to perform a Monte Carlo simulation the following information about the unit variable operating costs that will be generated by a project is as follows: Expected unit variable operating costs: $1,500 95% confidence interval forecast of unit variable operating costs: $1,240 to $1,760 If the above unit sales are distributed normally, compute the approximate standard deviation for unit variable operating costs. $130 $65 $260 O $1,040
