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

$\bar{x}=\frac{\sum_{i=1}^n}{6}=\frac{13+10+6+13+11+9}{6}=\frac{62}{6}=10.3$

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