1. **Stating the problem:** We are given a frequency distribution of red blood cell counts in intervals and their corresponding frequencies. 2. **Understanding the data:** The intervals and frequencies are: - 3.00-3.49: 1 - 3.50-3.99: 7 - 4.00-4.49: 14 - 4.50-4.99: 16 - 5.00-5.49: 17 - 5.50-5.99: 11 - 6.00-6.49: 8 - 6.50-6.99: 3 3. **Interpreting the histogram:** The histogram represents the frequency of red blood cell counts in each interval. 4. **Key points:** - The x-axis represents the red blood cell count intervals. - The y-axis represents the frequency of counts in each interval. - The highest frequency is 17 in the interval 5.00-5.49. 5. **Summary:** The data shows a distribution with frequencies increasing from 1 to 17 and then decreasing, indicating a roughly symmetric distribution centered around 5.00-5.49. This matches Graph A's description best, which has frequencies from 1 to 17 and the x-axis and y-axis labeled as described. Final answer: The frequency distribution corresponds to Graph A with the given intervals and frequencies.
