Question

a seventh grade student surveyed 25 students at her school. she asked them how many hours a week they spend playing a sport or a game outdoors.if there are 2,000 students at the school, what is you estimate for the number of students who would say they play a sport ir a game outdoors 4 hours a week? explain your answer

Answer 1

Let's begin by identifying key information given to us:

Number of students surveyed = 25

Survey breakdown: 3 students spend 0 hours, 4 students spend 1 hour, five students spend 2 hours, 7 students spend 3 hours, 3 students spend 4 hours, 2 students spend 6 hours, 1 student spends 1 hour

If total number of students = 2,000

The number of students who play a sport or outdoor game for 4 hours is given by:

`\begin{gathered} n=\frac{NumberOfStudentsWhoPlayFor4hours}{\text{Survey Sample}}\cdot TotalEstimatedSample \\ n=(3)/(25)\cdot2000=240 \\ n=240students \end{gathered}`

The estimate of students who play a sport or outdoor games for 4 hours amongst 2,000 students is 240
