Question was asked on:

For the first answer, set a confident interval – a range you are 90% sure contains the right answer. Levitin guessed that Chicago has around 2.5 million people because it is smaller than Los Angeles but large enough to house over 1.5 million residents. Next, Levitin supposed that a piano might need tuning once per year. Since pianos are too expensive for most families, Levitin guessed that 1/100 homes in Chicago own a piano. That number is doubled when you factor in schools, concert halls, etc. that possess more than one. 2.5 million residents x 2/100 (2%) = 50,000 pianos in Chicago. Then, Levitin guessed that it takes around two hours to tune a piano. Assuming that a piano tuner works 40 hours a week plus two weeks' vacation and spends about 20% of their time driving from job to job, the average piano tuner might work 1,600 hours per year.

In the context of the book, setting a confident interval is a method used in forecasting to estimate a range within which the correct answer is likely to fall. This is done with a certain level of confidence, usually 90%. The process involves making an educated guess based on available information and adjusting it as necessary. For instance, in the book, Levitin estimates the population of Chicago and the number of pianos in the city to eventually calculate the number of piano tuners. This method allows for a more flexible and potentially accurate prediction as it accounts for uncertainty and variability.

Startups and small businesses can use the concept of super forecasting for growth by applying it to their strategic planning and decision-making processes. Super forecasting involves making accurate predictions about the future based on data analysis, critical thinking, and probabilistic reasoning. This can help businesses anticipate market trends, customer behavior, and potential risks, allowing them to make informed decisions and take proactive measures. It can also be used to set realistic goals and track progress, which can drive continuous improvement and growth.
