We know that the confidence interval for the true proportion is given by:
And thats equivalent to:
We can estimate the estimated proportion like this:
And the margin of error can be estimaed using the fact that the confidence interval is symmetrical
And then the confidence interval in the form desired is:
bearing in mind that the centroid in a triangle cuts each of the three medians in a 2:1 ratio.
since we know that A C = 12, let's split it in a 2:1 ratio then, cleary from the picture the larger is F C, so F C : A F is on a 2:1 ratio.
