Now, there's many ways to approach it, but it looks like she is using a simulation. To see how likely a sample like this was to happen by random chance alone, Evie performed a simulation. She simulated 40 samples of n equals 25 students from a large population, where 6% of the students were vegetarian. She recorded the proportion of vegetarians in each sample. Here are the sample proportions from her 40 samples. So what she's doing here with the simulation, this is an approximation of the sampling distribution of the sample proportions if you were to assume that your null hypothesis is true. And it says below, Evie wants to test her null hypothesis, which is that the true proportion at her school is 6% versus the alternative hypothesis that the true proportion at her school is greater than 6%, where P is the true proportion of students who are vegetarian at her school.
