Large Counts Condition (one-sample) To check that the sampling distribution of p-hat is approximately normal, check that both the number of successes (n x p-hat) and the number of failures (n x (1-p-hat)) are at least 10 so that the sample size is large enough to support an assumption of normality One is the random condition. I'll write 'em up here. The random condition. And that would be that there's truly a random sample of games. And it tell us right here, he took a random sample of his 24 games.

Of course, it’s best if our sample size is much less than 10% of the population size so that our inferences about the population are as accurate as possible. The 10% condition states that sample sizes should be no more than 10% of the population. Whenever samples are involved in statistics, check the condition to ensure you have sound results. Some statisticians argue that a 5% condition is better than 10% if you want to use a standard normal model. For example, the 10% condition normally applies ... Learning Targets.
