Answer:
3.6
Step-by-step explanation:
First you would add up all the numbers, 4+3+9+2+3+4= 25
Then divide 25 by 7, because thats how many digits we have, so 25 divided by 7 would be 3.57142857143
To round to the nearest tenth (first place behind the decimal) We would round 5 up to 6. So the mean would be 3.6
