Question

Tom asked the 20 numbers of the football squad at his school how long they spend on the internet per evening. 7 of them spend over 4 hours per evening online. Tom used this information to estimate how many of the 1200 students are his school spend over 4 hours per evening on the internet. A) Assuming that Tom is good with numbers, What was his estimate?

Answer 1

Tom starts by calculating the ratio of football squad members who spend over 4 hours per evening online which is 7 out of 20. This gives him a ratio of 0.35.

Next, Tom wants to use this ratio to estimate how many students across the whole school spend over 4 hours per evening online. He makes the assumption that the patterns of internet use he observed in the football squad are representative of all 1200 students at the school.

So, he multiplies the total number of students, 1200, by the ratio of students who spend over 4 hours online which is 0.35.

By doing so, he estimates that around 420 students in the school spend over 4 hours per evening online.

In conclusion, Tom's estimation for the number of students at his school, who spend over 4 hours online per evening, is approximately 420 students. This result is based on the usage pattern he observed within his football team.
