In this problem, Jennie earns the first quartile salary for construction workers, and Markos earns the first quartile salary for teachers. The question asks who earns more and by how much.

To solve this:

1. **First Quartile (Q1) for Construction Workers:**
   - From the boxplot, the first quartile (Q1) for construction workers is approximately 30 thousand dollars.

2. **First Quartile (Q1) for Teachers:**
   - The first quartile for teachers appears to be around 35 thousand dollars.

3. **Who makes more?**
   - Markos, the teacher, earns more because his first quartile salary (35k) is higher than Jennie’s (30k).

4. **By how much more?**
   - The difference between Markos's and Jennie’s salaries is $ 35,000 - 30,000 = 5,000 $.

Thus, **Markos makes more by \$5,000**.

Here are 5 related questions for practice:
1. How do you find the interquartile range from a boxplot?
2. What does the median represent in a boxplot?
3. How can you tell which group has a higher salary range using a boxplot?
4. What is the range of salaries for construction workers based on the boxplot?
5. How would you interpret outliers on a boxplot?

**Tip:** When interpreting a boxplot, always note that the quartiles divide the data into four equal parts, with each part representing 25% of the dataset.

Jennie makes the first quartile salary for a construction worker. Markos makes the first quartile salary for a teacher. Who makes more money? How much more?

Learn how to compare salaries using boxplots by interpreting the first quartile data. In this example, Markos, a teacher, makes $5,000 more than Jennie, a construction worker, based on their first quartile salaries.
