A large school district knows that 75% of students in previous years rode the bus to school. Administrators wondered if that figure was still accurate, so they took a random sample of n = 80 students and found that p = 65% of those sampled rode the bus to school. To see how likely a sample like this was to happen by random chance alone, the school district performed a simulation. They simulated 120 samples of n = 80 students from a large population where 75% of the students rode the bus to school. They recorded the proportion of students who rode the bus in each sample. Here are the sample proportions from their 120 samples:
