IfSofie uses only the completed surveys, what conclusion could she make about the percent of all highschool students, who use social media while doing schoolwork?

Answer 1

QUESTION A

The survey is about finding out how many students use social media while doing schoolwork.

A question that can be asked is "How often do you access your social media account?"

QUESTION B

Sofie could go to different classrooms and hand out the survey to random students in the class. She could pick the students by selecting every fifth student to leave the class.

QUESTION C

The sample is 32 completed surveys and the population is a total of 80 surveys.

QUESTION D

Of the 32 students who completed surveys, 16 said they use social media while doing schoolwork. Therefore, the percentage is:

`\begin{gathered} P=(16)/(32)*100 \\ P=50\% \end{gathered}`

Therefore, she can conclude that 50% of the students use social media while doing schoolwork.
