The scatter plots below show the results of a survey of 20 randomly selected males ages
24dash–35.
Using age as the explanatory variable, match each graph with the appropriate description.
A scatter plot has a horizontal x-axis labeled
Age from 24 to 36 in increments of 2 and a vertical y-axis labeled In thousands of units from 0 to 100 in increments of 20. Twenty plotted points with integer horizontal coordinates follow a general pattern of rising from left to right at a constant rate.
A scatter plot has a horizontal x-axis labeled Age from 24 to 36 in increments of 2 and a vertical y-axis labeled In units from 60 to 80 in increments of 5. Twenty plotted points with integer horizontal coordinates appear to be randomly scattered within the rectangular area between horizontal coordinates 24 and 36 and between vertical coordinates 65 and 80. There is no obvious pattern in the points.
A scatter plot has a horizontal x-axis labeled Age from 24 to 36 in increments of 2 and a vertical y-axis labeled In thousands of units from 0 to 50 in increments of 10. Twenty plotted points with integer horizontal coordinates follow a general pattern of falling from left to right at a constant rate.
