Question

Quizplus · Accepted Answer

The sample size needed to generalize survey results to the whole population depends on many factors, including the size of the population, the margin of error desired, and the level of confidence desired. However, a commonly accepted rule of thumb is that a sample size of at least 1,200 is required for most surveys to produce statistically significant results that can be generalized to the whole population. Therefore, choice B (1,200) is the best choice.
