6. A survey asked 60 randomly chosen students if they eat school lunch. 40 said yes. There were 240 school lunches sold today. Predict the number of students who attend the school.

Based on the survey, we found that 40 out of 60 students eat school lunch, which gives us a proportion of approximately 66.67%. To predict the total number of students in the school, we can set up a proportion: if 66.67% of students eat lunch and 240 lunches were sold, we can calculate the total number of students. Dividing the lunches sold by the proportion gives: . So, there are about 360 students attending the school!

Now, it’s important to remember that survey samples can have inclination. The 60 students surveyed might not perfectly represent the entire school, so there could be some variation in actual attendance. Keep this in mind when making predictions based on surveys!
