Question

Describe the shape of the graph. Although the mean cannot be determined from the graph, can an approximation of the mean be determined? Explain.

(I'm having trouble on this, please help:,)

Answer 1

The graph above can be described as a symmetric graph.

The mean and median of the graph are nearly equivalent, creating symmetry.

Additionally:

The answer to the question after this is the 3rd option, "the average salary increased the same amount each year."

The second portion of the next question is the 2nd option, "The vertical axis does not begin at zero."

Answer 2

The graph is symmetric. The mean and median are about equal in a symmetric graph. The median is shown as 109, so the mean is approximately 109.

Explanation:

The graph is symmetric.

Because the graph is symmetric, the mean and median should be approximately equal.

According to the graph, the median is 109. Therefore, the mean is approximately 109.
