Answer 1

To determine which question should consider all sales associates (junior, mid-level, and senior) as one population, we need to analyze what each question is asking:

A. **Which group of associates worked the most combined hours?**
- This question compares groups (juniors, mid-level, seniors) against each other, hence they are considered separate populations.

B. **Who made the most sales from each group?**
- This question asks for the top salesperson from each group, meaning we are looking at multiple populations.

C. **What is the mean sales per associate for each group?**
- This question is asking for specific statistics from each group rather than treating them as a single population.

D. **How many associates received good customer service ratings?**
- This question can be answered cohesively for all associates, treating them as a single population since we are interested in the total count across all levels.

Based on this analysis, **the correct answer is:**

**D. How many associates received good customer service ratings?**

In this case, it makes sense to treat all associates as one population since we are summing or counting ratings, regardless of the group they belong to.
