To sketch: The graph showing the shape of the distribution of the bone mineral density test scores.
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
