Question

What is the "mean" of this number sequence? 4,2,2,2,5,15
A.5 B.2 C.13 D.4

Answer 1

(4+2+2+2+5+15)/6
=30/6=5

Answer 2

Answer:

The Mean of the given number sequence is 5

Step-by-step explanation:

Given that,the number sequence is 4,2,2,2,5,15

The number of observations(n)=6

we know that the mean is ratio of sum of observations to no.of observations.

Therefore,

$mean = \frac{sum \: of \: observations}{no.of \: observations}$

By substituting the given values in the above relation,we get

$mean = \frac{4 + 2 + 2 + 2 + 5 + 15}{6} = \frac{30}{6} = 5$

Therefore,the Mean of the given number sequence is 5
