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 ears passing through this intersection for a 24-hr period during a weekday. The graph of hourly traffic looks like this.
- a. At what time(s) does the highest number of cars pass through die intersection?
- b. At what time(s) does the lowest number of cars pass through die intersection?
- c. Briefly describe the trend in numbers of cars over the course of die day.
- d. Provide a hypothesis explaining the trend in numbers of cars over the course of the day.
- e. Provide a possible experiment that could test your hypothesis.

[A spectrophotometer is a scientific instrument that measures the amount of light (of a given wavelength) that is absorbed by the solution] The amount of light absorbed at a given wavelength of light (A) depends directly on the mass of compound per liter of solution. To calibrate the spectrophotometer, you collect the following data: Plot the absorbance (A) against the mass of copper compound per liter (g/L), and find the slope (m) and intercept (b) (assuming that A is y and the amount in solution is x in the equation for a straight line, y = mx + b).
