We live in a society obsessed with test scores and maximum performance. Think of the SAT, ACT, GRE, GMAT, and LSAT. Though they take only a few hours, they are supposed to give schools and companies a snapshot of a student's abiding talents. But these tests are often spectacularly bad at forecasting performance in the real world. The SAT does a decent job (r2 = 0.12) of predicting the grades of a college freshman. It is, however, less effective at predicting achievement after graduation. LSAT scores bear virtually no correlation to career success as measure by income, life satisfaction, or public service. What does r2 mean in this context? Is it ethical for colleges to base admissions and financial aid decisions on scores alone? What role do these tests have at your own school?

Senior executives at an oil company are trying to decide whether to drill for oil in a particular field. 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. What is the EMV if the company hires the expert?

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).
Please read the case and answer the following questions. CompStat (short for COMPuter STATistics or COMParative STATistics) originated in the New York City Police Department (NYPD) in 1994 when William Bratton was police commissioner. CompStat is a comprehensive, city-wide database that records all reported crimes or complaints, arrests, and summonses issued in each of the city’s 76 precincts. City officials had previously believed that crime could not be prevented by better information and analytical tools but instead by using more foot patrols in neighborhoods along with the concept of “community policing” in which efforts were made to strengthen the involvement of community groups. In contrast, Bratton and Rudy Giuliani, then the mayor of New York City, believed that. police could be more effective in reducing crime if operational decisions took place at the precinct level and if decision makers had better information. Precinct commanders were in a better position than police…

The article "New Product Blockbusters: The Magic and Science of Prediction Markets", discusses the importance of new product development in firms and the challenges associated with predicting the success of new products. The authors propose a novel approach to screening new product ideas and predicting their demand using prediction markets. According to the authors, research suggests new product introductions increase a firm's long-term financial performance and market value. The article discusses the challenges associated with predicting the success of new products. Only one out of every five new product launches are successful, and firms often fail to capitalize on the success of new product blockbusters because of poor demand forecasts. There are two common approaches to predicting new product demand: surveying target customers about their purchase intentions and pooling experts' opinions. However, there are limitations of these approaches and propose a novel approach using…
