Question

increasing the mean of a normal distribution results in which of the following changes?
○ it becomes skewed
○ it becomes narrower
○ it shifts right
○ it becomes taller

Explanation:

A normal distribution's shape (symmetry, spread, height) is determined by its standard deviation, not the mean. The mean defines the center of the distribution. Increasing the mean moves this center to the right without altering the distribution's shape, spread, or height.

Answer:

It shifts right
