Question

the graph represents a distribution of data. what is the mean of the data? 5 10 30 50

Explanation:

Step1: Recall the property of normal distribution

In a normal distribution (bell - shaped curve), the mean, median, and mode are equal. The peak of the curve represents the mode (and also the mean and median in a symmetric normal distribution).

Step2: Identify the peak position

Looking at the graph, the peak of the bell - shaped curve is at \(x = 50\).

Answer:

\(50\)
