If you were to graph precision (H)and sample size (n),which of the following generalizations would be most accurate?
A)Precision is very low with small sample sizes of 50 or below.
B)Precision constantly increases as sample size increases;a sample of 2,000 is four times more precise than a sample of 500.
C)Precision increases rapidly when sample size increases up to about 500 and then begins to level off.
D)Precision and sample size have nothing to do with each other,therefore graphing them make no sense
E)Both b and c are true.

As sample size increases, precision increases rapidly up to a point of about 500, after which it levels off. Option A is not entirely accurate since there may be instances where a small sample size can still yield high precision. Option B is not accurate because precision may not constantly increase at the same rate as sample size increases. Option D is inaccurate since precision and sample size have a positive correlation. Option E is not entirely accurate as option B is not true.
