Question
Chapter 6, Problem 1RE
To determine
To sketch: The graph showing the shape of the distribution of the bone mineral density test scores.
Expert Solution & Answer
Answer to Problem 1RE
The shape of the distribution of the bone mineral density test scores is shown below.
Explanation of Solution
Given info:
The bone density test scores follow a
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
