Question

A nationwide survey of a random sample of teenagers asked whether or not they played the saxaphone. The survey concluded that 4% of teenagers play the saxophone. Use this information to predict how many students in a school with 1000 students would play saxophone.

Answer 1

Answer: To predict the number of students in a school with 1000 students who play the saxophone, we can use the information from the nationwide survey, which states that 4% of teenagers play the saxophone.

First, we calculate the percentage of students in the school who are likely to play the saxophone:

Percentage of students playing saxophone = 4% = 0.04

Next, we multiply this percentage by the total number of students in the school to get the estimated number of students who play the saxophone:

Number of students playing saxophone = 0.04 * 1000 = 40

Therefore, based on the survey data, it is predicted that approximately 40 students in a school with 1000 students would play the saxophone.
