Suppose you join a new firm that uses Newsvendor model to compute how many "services" to prepare for the following day of selling. While the service is priced high (= $42.50 per unit), the cost of preparing services is quite high too (= $17 per unit). Further, the unsold units cannot be salvaged at all. Due to multiple turnovers in management of the firm, you have NOT been able to obtain any information about the daily demand, except that it is random and variable. However, as per the available notes, you know that the previous manager used to request preparation of 120 units each day in order to maximize the average profit. Based on this information, what is your best guess of the MEAN of the demand out of the following three options?
