![**Title: Analysis of Performers' Star Ratings in a Talent Competition**
**Introduction**
The data in the figure below represents the number of stars earned by 140 performers in a talent competition. The graph provides a visual representation of the distribution of star ratings among the performers.
**Graph Description**
- **X-Axis (Number of Stars):** This axis represents the number of stars awarded to the performers, ranging from 0 to 5.
- **Y-Axis (Percentage of Performers):** This axis represents the percentage of the total 140 performers who received each star rating, ranging from 0% to 35%.
- **Data Bars:** Each bar indicates the percentage of performers who earned a specific number of stars.
**Graph Analysis**
Detailed observations from the graph:
- **0 Stars:** Approximately 10% of the performers received 0 stars.
- **1 Star:** Around 15% of the performers received 1 star.
- **2 Stars:** A significant 30% of the performers received 2 stars, the highest percentage among all ratings.
- **3 Stars:** About 20% of the performers received 3 stars.
- **4 Stars:** The percentage decreases to approximately 5% for those who received 4 stars.
- **5 Stars:** Similarly, around 5% of the performers received 5 stars as well.
**Question for Analysis**
How many performers earned exactly 3 stars? (Be careful - compare the question wording to the scale on the graph)
**Calculation Technique**
To find the number of performers who earned exactly 3 stars:
1. Identify the percentage of performers who earned 3 stars from the graph, which is 20%.
2. Calculate the number of performers: \[(20\% \times 140 performers) = 28 performers\]
