Question

On a survey, 8 students reported how many minutes it takes them to travel to school. Here are their responses.9, 11, 3, 14, 14, 7, 14, 6Find the mean travel time for these students.If necessary, round your answer to the nearest tenth.

Answer 1

The arithemetic mean of a set of data is the sum of the datas divided by the number of data given.

Hence

`\begin{gathered} \text{Mean}=\frac{sum\text{ of the data}}{n} \\ \text{where n= number of student=8} \end{gathered}`

Given the set of data below

`9,\: 11,\: 3,\: 14,\: 14,\: 7,\: 14,\: 6`

The sum of the data is

`9+11+3+14+14+7+14+6=78`

Hence

`\text{Mean}=(78)/(8)=9.75`

The mean travel time for these students is 9.8 minutes to the nearest tenth.
