![**Understanding Normal Distribution and Calculating Shaded Area Under the Curve**
**Problem Description:**
Find the area of the shaded region. The graph depicts the standard normal distribution of bone density scores with mean \(0\) and standard deviation \(1\).
**Graph Analysis:**
The graph shown represents a standard normal distribution curve, which is a bell-shaped curve centered at the mean \(0\) with a standard deviation of \(1\). The shaded region under the curve indicates the area we aim to calculate. This area lies to the right of the z-score \(z = -1.13\).
**Calculation Task:**
Determine the area of the shaded region to the right of \(z = -1.13\).
**Input Box:**
- The area of the shaded region is: [Input Box] (Round to four decimal places as needed.)
**User Instruction:**
Enter your answer in the input box provided.

**Technical Explanation:**
The area under the standard normal distribution curve can be determined using z-tables or statistical software. For a given z-score, the area to the right of the z-score can be found by:
1. Finding the cumulative probability for \(z = -1.13\).
2. Subtracting this cumulative probability from 1 to get the area to the right of \(z = -1.13\).
This calculated area represents the probability or proportion of observations that lie to the right of \(z = -1.13\) in a standard normal distribution.
**Educational Note:**
Understanding how to interpret and compute areas under the normal distribution curve is fundamental in statistics, particularly in finding probabilities and making inferences about population parameters based on sample data.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fdbedd374-d5ca-41f2-a379-751fa7b6bb2f%2F85a7204d-fe68-428f-b445-77bd670f5fee%2Fr2b7bd4.jpeg&w=3840&q=75)
