The component is one game I’ll generate random numbers and assign numbers from 00 to 54 to the home team’s winning and from 55 to 99 to the visitors’ winning. I’ll generate components until one team wins 4 games. I’ll record which team wins the series. The response is who wins the series.

I’ll calculate the proportion (%)of wins by the team that starts at home.

Skip 57–99. If I get a number in this range, I’ll throw it away and go back for another two-digit random number, also ignore repeats Each trial consists of identifying pairs of digits as V (varsity) or N (nonvarsity) until 3 people are chosen, ignoring out-of-range or repeated numbers (X)—I can’t put the same person in the room twice The response variable is whether or not all three selected students are on the varsity team.

Determine the % of trials that had “all varsity “ roommates to determine how likely that was to happen if it was truly fair “All varsity” occurred once, or 10% of the time. In my simulation of “fair” room draws, the three people chosen were all varsity team members only 10% of the time. While this result could happen by chance, it is not particularly likely. I’m suspicious, but I’d need many more trials and a smaller frequency of the all-varsity outcome before I would make an accusation of unfairness.
