4. Assume that Wynona's sales projections come from a normal distribution and the weighted average price of the mix of guitars sold by Nelson is $890 per guitar. Superimpose onto the graph created for Question 2 a probability distribution of sales with an expected sales level, E(Q), of 5,000 units and a standard deviation of l,l|| units. (Be sure the left tail of the probability distribution extends beyond the breakeven level of output for the current production method.) What is the expected net operating income, E{NOI), and the probability of an operating loss with the current technology? With the proposed technology? Identify the areas of operating loss with each technology under the probability distribution
