In a normal distribution, which statement is true?

Explanation:
Symmetry around the center is the key idea. In a normal distribution, the data mirror each other on the left and right sides, so the center is the balance point and also the middle value. Because the mean measures balance and the median marks the middle, they coincide in a normal distribution. That means the mean equals the median. The other statements would imply some skew or imbalance, which a normal distribution does not have. It isn’t skewed to the left; it’s perfectly symmetric.
