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 his students live from the school is 4.2 miles.
Mean value
The mean value has defined the ratio of the sum of all numbers and total number.
Given information
Principal Phillipi used a random sample of 20 students 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.
The following formula is used to determine the mean value;
[tex]\rm Mean = \dfrac{Sum \ of \ all \ data}{Number \ of \ data}[/tex]
The mean distance that his students live from the school is;
[tex]\rm Mean = \dfrac{Sum \ of \ all \ data}{Number \ of \ data}\\\\\rm Mean = \dfrac{3+ 4+ 5 + 3 + 4 + 5+ 6+ 5+ 4+ 3 + 2 + 3+ 4+ 5+ 6 + 4+ 8 + 4 + 3 + 2 }{20}\\\\Mean = \dfrac{83}{20}\\\\Mean = 4.2[/tex]
Hence, the mean distance that his students live from the school is 4.2 miles.
