Step-by-step explanation:
In a symmetric distribution, the left side of the distribution mirrors the right side. Therefore, because of being 'identical' on both sides, the frequencies are symmetrically spread across the distribution.
One implication of such symmetry is that the mean, mode, and median are at the same point. Then, if the mean is 245, the median has to be 245 too.
<h2>The answer is option A, 245</h2>
