Answer:
The standard deviation of the sample mean is
Step-by-step explanation:
From the question we are told that
The mean is
The standard deviation is
The sample size is
Generally the standard deviation of the sample mean is mathematically represented as
substituting values
1, 3, 5, 7, 9 ......
notice, there are consecutive odd integers, every other number
skip one, another, skip one, another and so on
so, from 1 to 3, is 1 + 2 =3
5 is 3 +2
7 is 5+2
and so on
let us pick an odd integer, hmmm say "a"
to find the next odd one, it'd be "a + 2" of course :)
we know their sum is 316
so
once you found "a", the next one is, well, "a + 2" :)
