Principal Phillipi used a random sample of 20 student records to determine how far, in miles, students live from the school. The results are shown below.

3, 4, 5, 3, 4,
5, 6, 5, 4, 3,
2, 3, 4, 5, 6,
4, 8, 4, 3, 2

What is the mean distance that his students live from the school, rounded to the nearest tenth?

4.15

Step-by-step explanation:

Mean is calculated by total sum of student records/ number of students records

From the question, total sum is 83, while the number of students records is 20

Divide 83 by 20 to get the mean

Mean = 83/20 = 4.15

I hope this is clear, please mark as brainliest
