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? 4.1 miles

8.0 miles
8.3 miles
Answers
Answer:
To find the mean:
Take 3 4 5 3 4 5 6 5 4 3 2 3 4 5 6 4 8 4 3 2 and add them all together
=83
Now you divide 83 by the number of terms in the sample set, which is 20.
83/20 = 4.15
For rounding to the nearest tenth, look at the hundredths space, which is 5. Since it is 5 or higher, round the tenths up one.
final answer= 4.2
The mean distance that students live from the school is 3.6 miles. Rounded to the nearest tenth, it is 4.1 miles.
So, the answer is 4.1 miles.
To find the mean distance that students live from the school.
we need to calculate the sum of all the distances and divide by the total number of students.
Sum of distances = 3+4+5+3+4+5+6+5+4+3+2+3+4+5+6+4+8+4+3+2 = 72
Total number of students = 20
Mean distance = Sum of distances / Total number of students = 72 / 20 = 3.6
Therefore, the mean distance that students live from the school is 3.6 miles. Rounded to the nearest tenth, it is 4.1 miles.
So, the answer is 4.1 miles.
