Bone Density Test. In Exercises 1–4, assume that scores on a bone mineral density test are normally distributed with a mean of 0 and a standard deviation of 1.

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

Features Features Normal distribution is characterized by two parameters, mean (µ) and standard deviation (σ). When graphed, the mean represents the center of the bell curve and the graph is perfectly symmetric about the center. The mean, median, and mode are all equal for a normal distribution. The standard deviation measures the data's spread from the center. The higher the standard deviation, the more the data is spread out and the flatter the bell curve looks. Variance is another commonly used measure of the spread of the distribution and is equal to the square of the standard deviation.

Elementary Statistics, Books A La Carte Edition (13th Edition), Chapter 6, Problem 1CQQ

Explanation of Solution

Given info:

The bone density test scores follow a normal distribution with mean of 0 and standard deviation of 1.

Justification:

Here, the bone density test follows a normal distribution. Also, the graph of the normal distribution is bell shaped and is symmetric about the mean. Moreover, if the mean and standard deviation are 0 and 1, respectively, the distribution is known as standard normal distribution. Hence, the graph of the bone density test scores is bell-shaped
