A group of people were asked if they had run a red light in the last year. 168 responded "yes", and 399 responded "no".

Let's analyze the given data. The total number of people surveyed is the sum of those who answered "yes" and those who answered "no":

\[
\text{Total} = 168 + 399 = 567
\]

Next, we can find the proportions of people who responded "yes" and "no".

### Proportion of "Yes" responses:
\[
\frac{168}{567} \approx 0.296
\]
This means about 29.6% of the people responded that they had run a red light.

### Proportion of "No" responses:
\[
\frac{399}{567} \approx 0.704
\]
This means about 70.4% of the people responded that they had not run a red light.

Here are 5 follow-up questions related to this scenario:

1. What is the percentage of people who answered "yes"?
2. How can we interpret this data to infer risk factors for running red lights?
3. What statistical methods could be used to analyze trends in traffic violations?
4. How might a different sample size affect the accuracy of the results?
5. How would we calculate the odds ratio between those who run red lights and those who don’t?

**Tip:** When working with survey data, always ensure that the sample size is large enough to draw meaningful conclusions.
