![**Understanding Normal Distribution and Standard Normal Curve**
---
**Normal Distribution**
Below is a graph of a normal distribution with a mean \( \mu = -3 \) and a standard deviation \( \sigma = 4 \). The shaded region represents the probability of obtaining a value from this distribution that is less than 3.
*Graph Description:*
The graph depicts a bell-shaped curve, which is symmetrical around its mean, \( \mu = -3 \). The x-axis ranges from approximately -11 to 7. The y-axis indicates the probability density, ranging from 0 to 0.4. The shaded area covers the region under the curve from the leftmost part extending up to x = 3.
---
**Standard Normal Distribution**
Shade the corresponding region under the standard normal density curve below.
*Diagram:*
The second diagram is a standard normal distribution curve where we need to shade the area corresponding to obtaining a value less than 3 in the standard normal form. The mean of the standard normal curve is 0, and the standard deviation is 1. This curve is also bell-shaped and symmetric around the mean. Shading for the standard normal curve must reflect the equivalent probability region as highlighted in the first graph.
---
**Graphical Representation:**
- First Graph: Shows the area under a normal distribution curve with \( \mu = -3 \) and \( \sigma = 4) \ shaded to represent the probability for values less than 3.
- Second Graph: Is a standard normal distribution curve to be shaded (not shown represented in the provided image).
**Graphical Interaction Tools:**
Below the graph, there are interactive tools for shading, provided to enhance the students' understanding.
*Explanation*:
An additional 'Explanation' button may provide detailed steps on how the shading corresponds between normal and standard normal distributions.
*Check*:
A 'Check' button allows students to verify the correctness of their shaded region.
---
*Note: Ensure to use the interactive tools to practice shading and understanding the transition from a normal distribution to a standard normal distribution.*
