The senior class president of a large university claimed that 40% of the senior class was interested in going on the senior trip. To test this claim, the senior class president conducted a survey of a random sample of 40 seniors and 9 said that they wanted to go on the senior trip. To better understand the significance of the survey results, a simulation was devised based on the claim that 40% of the seniors wanted to go on the trip, each of sample size 40, simulated 100 times. Explain how the results of the simulation can be used to support or refute the senior class president's claim.
