You can put this solution on YOUR website! ```python?code_reference&code_event_index=1
data = {
"Calls": ["1-4", "5-8", "9-12", "13-16", "17-20"],
"Frequency": [14, 12, 6, 2, 1]
}
# 1. Total people surveyed
total_people = sum(data["Frequency"])
# 2. Less than 5 calls (This is the 1-4 bracket)
less_than_5 = 14
# 3. At least 13 calls (This is 13-16 and 17-20)
at_least_13 = 2 + 1
percentage_at_least_13 = (at_least_13 / total_people) * 100
print(f"Total surveyed: {total_people}")
print(f"Less than 5: {less_than_5}")
print(f"At least 13: {at_least_13}")
print(f"Percentage: {percentage_at_least_13}")
```
```text?code_stdout&code_event_index=1
Total surveyed: 35
Less than 5: 14
At least 13: 3
Percentage: 8.571428571428571
```
Based on the table provided, here are the calculations for the survey results.
### **1. How many of the people surveyed make less than 5 calls per day?**
The category for "less than 5" is the **1 - 4** calls bracket.
* **Number of people:** **14**
---
### **2. How many people were surveyed?**
To find the total, we sum the frequencies of all categories:
* $14 + 12 + 6 + 2 + 1 = 35$
* **Total surveyed:** **35**
---
### **3. What percentage of those surveyed make at least 13 calls per day?**
"At least 13" includes the categories **13 - 16** and **17 - 20**.
* **Number of people:** $2 + 1 = 3$
* **Calculation:** $\frac{3}{35} \times 100 \approx 8.57\%$
* **Rounding to the nearest whole number:** **9%**
---
### **Summary of Answers**
* How many make less than 5 calls: **14**
* How many people were surveyed: **35**
* Percentage making at least 13 calls: **9%**
