Question

What is mu equal to?

The image illustrates a bell-shaped curve, representing a normal distribution. The horizontal axis displays a numerical scale with key points marked at -2, 4, and 6. The value "σ=4" indicates that the standard deviation (σ) is 4 units. The central shaded region beneath the curve spans from -2 to 6 on the horizontal axis and encompasses approximately 68% of the total area under the curve. This shaded area signifies the range within one standard deviation from the mean in a normal distribution, indicating that roughly 68% of the data falls within this range.
