Question

On a survey, 6 students reported how many minutes it takes them to travel to school. Here are there responses find the mean travel time for these students. IF NECESSARY ROUND YOUR ANSWER T I THE NEAREST TENTH

Answer 1

`\bar{x}=10.3`

1) Considering that these are the number of minutes taken by those 6 students:

`13,10,6,13,11,9`

2) Then, we can find the mean by adding up all those times divided by the number of entries: 6

`\bar{x}=(\sum_(i=1)^n)/(6)=(13+10+6+13+11+9)/(6)=(62)/(6)=10.3`

Note that when it comes to mean, we don't need to write the entries in ascending order.
