Question
![**Survey on Pet Ownership at a Pet Store**
In a survey conducted at a pet store, 150 customers were asked if they owned birds or fish. The survey data are shown in the relative frequency table below:
| | **Own a bird** | **Do not own a bird** | **Total** |
|-------------------|---------------|---------------------|---------|
| **Own fish** | 0.04 | 0.06 | |
| **Do not own fish** | 0.02 | 0.88 | |
| **Total** | | | |
**Interpretation of the Table:**
- **Own fish and own a bird:** The relative frequency is 0.04.
- **Own fish and do not own a bird:** The relative frequency is 0.06.
- **Do not own fish and own a bird:** The relative frequency is 0.02.
- **Do not own fish and do not own a bird:** The relative frequency is 0.88.
**Question:** What percentage of the people surveyed own fish?
**Calculation:** To find the percentage of people surveyed who own fish, sum the relative frequencies of those who own fish (both those who own a bird and those who do not):
\[
0.04 + 0.06 = 0.10
\]
Therefore, 10% of the people surveyed own fish.](https://content.bartleby.com/qna-images/question/e5e18cbe-2086-4486-bcaa-95b482346f76/82482e54-8a3e-4c82-ae2f-e06bf0affa9d/5doqf3_processed.jpeg)
