Statistics & Probability Flashcards: Evaluating Models With Data And Simulation

Study Evaluating Models With Data And Simulation in Statistics & Probability with focused flashcards that help you recognize the idea, recall the key rule, and apply it in practice-style prompts.

QUESTION

What is the main reason to run many simulation repetitions (for example, $10{,}000$ ) instead of few?

ANSWER

More repetitions reduce random simulation error in the estimated probability. Law of large numbers ensures convergence to true probability.

A survey company claims that

P(\text{supports the proposal})=0.40

for the population. They survey 80 people and find 28 support the proposal. You simulate 100 samples of 80 people each using

P=0.40

. In the simulations, 41 out of 100 samples had 28 or fewer supporters ("as extreme or more extreme" means

\le 28

). Which conclusion is most reasonable?
