In a normal distribution, the mean, median, and mode are equal. The graph is a normal distribution curve.

Step2: Identify the peak of the normal distribution

The peak of the normal distribution (which represents the mode) occurs at \(x = 50\). Since for a normal distribution \(\mu=\text{Mode}\) (where \(\mu\) is the mean).
