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.

Answer the questions to solve the problem.
1. How many students did the teacher survey?

The teacher surveyed 210 students.

2. What is the relative frequency of a student choosing the aquarium? Give your answer as a decimal rounded to the nearest hundredth. Show your work.

The relative frequency is 0.38 for the aquarium.
80 * 210 = 0.380. Rounded to Nearest hundredth is 0.38

3. Suppose the teacher surveys one student at random. Based on the survey results, what is the estimated probability that the student chooses the aquarium?

The percentage of the probability of that student choosing the aquarium is 38%.

4) Write and solve a proportion that the teacher can use to estimate how many students in the whole school would choose the aquarium. Show your work.
