As part of a science project, you study traffic patterns in your city at an intersection in the middle of downtown. You set up a device that counts the cars passing through this intersection for a 24-hour period during a weekday. The graph of hourly traffic looks like this. At what lime(s) does the highest number of cars pass through the intersection? At what time(s) does the lowest number of cars pass through the intersection? Briefly describe the trend in numbers of cars over the course of the day. Provide a hypothesis explaining the trend in numbers of cars over the course of the day. Provide a possible experiment that could test your hypothesis.

Interpretation:

We need to determine the time when the highest number of cars pass through the intersection.

Concept Introduction:

We study traffic patterns in a city at an intersection in the middle of downtown. The device that counts the number of cars passing through this intersection for a twenty four hour period on a weekday is set up. The graph of the hourly traffic is shown.

Interpretation:

We need to form a hypothesis explaining the trend in the number of cars passing through this intersection each day.

Interpretation:

We need to create and perform the experiment which will test the hypothesis.

Concept Introduction:

We study traffic patterns in a city at an intersection in the middle of downtown. The device that counts the number of cars passing through this intersection for a twenty four hour period on a weekday is set up. The graph of the hourly traffic is shown. Based on the graph, we try to test the hypothesis.
