Bone Density Test. In Exercises, assume that scores on a bone mineral density test are normally distributed with a mean of 0 and a standard deviation of 1.

Sketch a graph showing the shape of the distribution of bone density test scores.

Step 1 of 1</p>

We have to assume that scores on a bone mineral density test are normally distributed with a mean of 0 and a standard deviation of 1.

The claim is to sketch a graph of the distribution of bone density test scores.

Properties of a Normal Distribution

1. The mean, median, and mode are equal.

2. The normal curve is bell-shaped and is symmetric about the mean.

3. The total area under the curve is equal to one.

4. The normal curve approaches, but never touches, the x-axis.

5. Between µ − σ and µ...
