A teacher surveys a sample of students from Lake Middle School. He asks the students where they’d like to go for a field trip. He records these results: 80 choose the aquarium.
60 choose the science center.
30 choose the planetarium.
40 choose the farm.
The teacher wants to figure out the relative frequency of a student choosing the aquarium. He will then estimate how many students out of all 1000 at the school are likely to choose the aquarium.
