b.
To construct: The figure that shows the relationship between the number of accidents and time.
b.
Explanation of Solution
Graph:
The figure is:
c.
To discuss: The point that is highlighted by part (a) not part (b).
c.
Explanation of Solution

d.
To discuss: The point that is highlighted by part (b) not part (a).
