Question

The following table represents a grouped frequency distribution of the number of hours spent on the computer per week for 53 students. What percentage of students used the computer less than 11 hours per week? Round your answer to the nearest tenth, if necessary.

Answer 1

Given:

Total number of students = 53

Required: Percentage of students used the computer less than 11 hours

Step-by-step explanation:

Number of students used the computer less than 11 hours

`\begin{gathered} =5+17 \\ =22 \end{gathered}`

Percentage of students used the computer less than 11 hours

`\begin{gathered} =(\frac{\text{ Number of students used the computer less than 11 hours}}{\text{ Total number of students}}\cdot100)\% \\ =((22)/(53)\cdot100)\% \\ =0.42\% \end{gathered}`
