Question

identify the mean of each distribution.
distribution a
mean =
distribution b
mean =
distribution c
mean =

Explanation:

Identify the line of symmetry for each curve

Using the Normal Distribution and Symmetric Distribution knowledge points

• For a symmetric normal distribution curve, the mean is located exactly at the horizontal position of its peak.
• Distribution A (orange curve): The peak is centered directly above the tick mark labeled \(50\).
• Distribution B (blue curve): The peak is centered directly above the tick mark labeled \(100\) (the midpoint between \(50\) and \(150\)).
• Distribution C (green curve): The peak is centered directly above the tick mark labeled \(200\) (the midpoint between \(150\) and \(250\)).
