And so right here it says, look, the sample size times our sample proportion has to be greater than or equal to 10. Or our sample size times one minus our sample proportion has to be greater than or equal to 10. Well, another way to think about this is our successes, our successes in our sample need to be greater than or equal to 10. And our failures need to be greater than or equal to 10. Well, how many successes were there? There were seven, seven. And you could even say, look, our n is 30 times our sample proportion is seven over 30, which is going to be seven.
