Find the mean travel time for these students.
If necessary, round your answer to the nearest tenth.

Answer 1

Answer:7.9

Step-by-step explanation:

To find the mean, you need to add all of the numbers you have and divide the total sum by how many numbers you have. (Sorry if it's confusing I'm bad at putting things into words)

So, you'd add the students' responses first.

8+4+4+10+8+6+15=55

Then, you'd divide the sum (55) by the number of responses (7).

55/7=A really long decimal so we're just gonna round it

55/7≈7.9
