Suppose that you work at a local food
manufacturer and are given the task of
investigating your company's seasonal sales
patterns over the past 10 years (2011 to
2020). After adjusting your sales values for
inflation, you calculate the following
seasonal sales averages (in millions):
Spring: 39
Summer: 46
Fall: 32
Winter: 23
Use this information to seasonally adjust
your 2021 Winter sales total of 29 million.
Round your answer to two decimal points
and omit any units (1.23 NOT $1.23 million).
A television network earns an average of $25 million each season from a hit program and loses an average of $8 million each season on a program that turns out to be a flop. Of all programs picked up by this network in recent years, 25% turn out to be hits and 75% turn out to be flops. At a cost of C dollars, a market research firm will analyze a pilot episode of a prospec- tive program and issue a report predicting whether the given programwill end up being a hit. If the program is actually going to be a hit, there is a 75% chance that the market researchers will predict the program to be a hit. If the program is actually going to be a flop, there is only a 30% chance that the market researchers will predict the program to be a hit.a. What is the maximum value of C that the network should be willing to pay the market research firm?b. Calculate and interpret EVPI for this decision problem.

- Arçelik Refrigerator Production Inc. manufactures various types of refrigerators. Currently, it has produced the AA-No Frost type refrigerator and wants to do a research on its market value. The company identified its 6-person expert housewife customer and requested the valuation of the AA-No Frost refrigerator. These customers use a similar type of General Electric refrigerator, and the General Electric refrigerator value is -0.5352 in the valuation of this refrigerator. Values are determined out of 1000. According to this information, what is the value of the AA-No Frost refrigerator?

If this new product succeeds in the marketplace, C&B estimates that it could earn $1,800,000 in future profits from the sale of the new toothpaste. If this new product fails, however, the company expects that it could lose approximately $750,000. If C&B chooses not to market this new brand, the product manager believes that there would be little, if any, impact on the profits earned through sales of C&B’s other products. The manager has estimated that the new toothpaste brand will succeed with probability 0.50. Before making her decision regarding this toothpaste product, the manager can spend $75,000 on a market research study. Based on similar studies with past products, C&B believes that the study will predict a successful product, given that product would actually be a success, with probability 0.75. It also believes that the study will…arrow_forward

It costs the company $750,000 to drill. The company estimates that if oil is found the estimated value will be $3,650,000. At present, the company believes that there is a 48% chance that the field actually contains oil. Before drilling, the company can hire an expert at a cost of $75,000 to perform tests to make a prediction of whether oil is present. Based on a similar test, the probability that the test will predict oil on the field is 0.55. The probability of actually finding oil when oil was predicted is 0.85. The probability of actually finding oil when no oil was predicted is 0.2.
