We don't know his methodology of what he considers random, but we'll take their word for it that yes, this has been met. The data is a random, random sample. If it said he sampled the football team, well, that would not have been a random sample. The next condition here, it looks all mathematical, but this is really the normal condition. And the idea behind the normal condition is that in order to construct these confidence intervals, we're assuming that the sampling distribution of the sample proportions is roughly normal. And it is not skewed to the right or skewed to the left like this. And so right here it says, look, the sample size times our sample proportion has to be greater than or equal to 10.
