Question

Principal Philippi use 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 10th?

Answer 1

Answer:  Your answer would be 4.2

Answer 2

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
