As given by the question
There are given that the survey of 7 students:
[tex]6,\text{ 5, 16, 3, 12, 15, 8}[/tex]
Now,
From the formula to find the mean:
[tex]\operatorname{mean}=\frac{\text{Addition of the total given data}}{\text{Total number of data}}[/tex]
Then,
[tex]\operatorname{mean}=\frac{6+5+16+3+12+15+8}{7}[/tex]
Then,
[tex]\begin{gathered} \operatorname{mean}=\frac{6+5+16+3+12+15+8}{7} \\ \operatorname{mean}=\frac{65}{7} \\ \operatorname{mean}=9.3 \end{gathered}[/tex]
Hence, the mean travel time is 9.3 minutes
