Order the steps in the process for finding the order quantity that maximizes expected profit
1. Evaluate the critical ratio 2. Find the z value that corresponds to the critical ratio 3. Use the z value to calculate the optimal order quantity for the true demand distribution
To compute expected sales for a given order quantity you need to know or compute which of the following:
1. expected inventory 2. the order quantity
The newsvendor model is appropriate for a setting where a customer will wait for the next shipment to show up in cases where a store runs out of inventory - True or False?
False
What is the salvage value?
The price at which units are units are sold at the end of the selling season
Expected profit is also based on the consequences of inventory that needs to be salvaged - True or false?
True

The larger the critical ratio the ... the order quantity that maximizes expected profit
larger

Which of the following factors are involved in the calculation of expected profit?
order quantity, expected inventory, expected sales
The density function returns the ______ a given outcome occurs
probability
To derive the optimal order quantity for the true demand distribution from the optimal order quantity for the standard normal distribution, multiply the ___ of the true demand distribution by the optimal order quantity for the standard normal distribution.
standard deviation
When z=-1, the optimal order quantity should be one ... below the mean of the actual demand distribution
standard deviation
When z=2, the optimal order quantity should be two ___ ___ above the mean of the actual demand distribution
standard deviations
Expected sales measures those sold at ______ price
the regular
Match the outcome with the "pain"
too much - inventory sold at a deep discount too few - lost sales and profits
