Analyze decisions and strategies with probability concepts in applied settings.
Compare simulated strategy averages and variability under a stated screen
Problem
A \(10,000\text{-}\text{trial}\) simulation gives mean payoff \(\$2.10\) for Strategy A and \(\$1.80\) for Strategy B. Under the stated screen, call the higher mean meaningfully higher only when there are at least \(1,000\) trials and the absolute mean gap is at least \(\$0.25\). No spread measure is reported. Which conclusion is supported by the screen?
Big Picture
What this problem is really about
A simulation screen and a variability claim require different evidence. We’ll compute the observed mean gap, test the sample size and gap against their separate thresholds, classify only what that screen supports, and then check whether any spread statistic is available before discussing variability.
