Using the Central Limit Theorem, it is found that the standard error for this sample is of 1.67.

<h3>What does the Central Limit Theorem state?</h3>

It states that for a population of standard deviation $\sigma$ , the sampling distribution of sample means of size n has standard error $s = \frac{\sigma}{\sqrt{n}}$ .

In this problem, we have that $\sigma = 10, n = 36$ , hence the <em>standard error</em> is given by:

$s = \frac{10}{\sqrt{36}} = 1.67$

You must be given with the point of the whole line. Knowing that you would have 4 equal parts, there must be 5 divisions. The first thing to do is find the midpoint of the endpoints of the line to create a mid-partition. You now have 2 equal parts. Next, find the midpoint again for the 2 equal parts. You make 2 new parts again for each side. The total would be 4.

To find the midpoint, just find the average of the corresponding x- and y-coordinates of the 2 points. If point A(1,2) and point B is (3,4), the midpoint would be (2, 3).
