Use the information below to select the closest answer to the following questions. If you need to calculate the z-value based on a given probability (or vice versa), you can either use Excel or the table at https ///wwwmatharizonacedu/ rrsims/ma464/standardnormaltabl . - Publisher's selling price to newsvendor: $0.70 per unit - Newsvendor's selling price to customers: $1.00 per unit - Newsvendor's salvage value for unsold items: $0.10 per unit - Demand is normally distributed with an average of 100 and a standard deviation of 40. Question 1: The understocking cost is $ , the overstocking cost is $ , and the critical ratio is [ Select ]. Question 2: The optimal order quantity is units. Question 3: Following the optimal ordering policy, the retailer will run out of stock with a probability of Question 4: If the newsvendor orders 79 units, it will be facing a in-stock probability. Question 5: Assume that the newsvendor purchases 72 units in the morning and looks at an expected (unsold) inventory of 6 units. The newsvendor's expected profit is $162. Question 6: Now assume that the newsvendor cannot earn the salvage value of the product at the end of the day, but has to pay $0.20 per unit to dispose of any unsold item. The critical ratio is recalculated as
