### Understanding Probability with Bone Density Test Scores

Assume that a randomly selected subject is given a bone density test. For this example, test scores are normally distributed with a mean of 0 and a standard deviation of 1. We are interested in finding the probability that a given score falls between -2.01 and 3.74. 

#### Task:
1. Find the probability that a test score is between -2.01 and 3.74.
2. Draw a sketch that represents this probability.

#### Graphical Representation:
Choose the correct graph from the options below, which highlights the region of the normal distribution curve for the specified range.

**Options:**
- **A.** A graph with the region between -2.01 and 3.74 shaded.
- **B.** A graph with the region outside -2.01 and 3.74 shaded.
- **C.** A graph with the region outside -2.01 and 3.74 shaded. The shaded area covers from negative infinity to -2.01 and from 3.74 to positive infinity.
- **D.** A graph with the region between -2.01 and 3.74 shaded.

#### Question:
Which graph correctly represents the shaded region for the probability that a score is between -2.01 and 3.74?

#### Answer:
Graph **A** and **C** both correctly highlight the region between -2.01 and 3.74, which is the area of interest for our calculation. 

#### Probability Calculation:
The probability is \[ \boxed{0.9785} \]
(Note: Please calculate using appropriate statistical tools if necessary)

### Conclusion:
By understanding how to read and interpret these normal distribution graphs, we can easily determine the region of interest and calculate the associated probabilities. This is a fundamental skill in statistics, particularly in applied fields such as medical testing and research. 

#### Note:
Always round off your answers to four decimal places unless stated otherwise.
