1. Problem Description
The state Department of Transportation wants to study out-of-state vehicles that pass over a toll bridge. A camera is installed on one lane of the bridge and photographs the license plate of every tenth vehicle that passes through that lane. We need to identify the population and the sample in this setting.
2. Solution Steps
The population is the entire group that the study wants to know about. In this case, it's about the vehicles that pass through the lane with the camera.
The sample is the subset of the population that the data is collected from. In this case, it's every tenth vehicle that passes through the lane with the camera.
Therefore, the correct answer is: The population is all of the vehicles that pass through the lane with the camera; the sample is the group of every tenth vehicle that passes through the lane.
3. Final Answer
