I think the correct answer from the choices listed above would be the third option. The city that is the leading industrial producer and financial center in South America would be Sao Paolo, Brazil. Hope this answers the question. Have a nice day.
Sao Paolo is a remarkable city. It is located in the southeastern part of Brazil. This city has experienced, and still is, a rapid development, and also its economic power is growing with each year, making it not just a regional center, but a city that is starting to have influence on the global market as well. Because of this, Sao Paolo has earned the nickname ''the South American Detroit''.
Samples are used in statistical testing when population sizes are too large for the test to include all possible members or observations. A sample should represent the population as a whole and not reflect any bias toward a specific attribute.
