Question 4(Multiple Choice Worth 2 points) (04.01 MC) FreezeFrame, a social networking site, sent out a survey in which the users simply click a response to join the sample. One of the questions in 2015 was, "Do you prefer to shop online?" More than 45,000 people responded, with $$ 79 \% $$ responding yes. What can you conclude from the survey? About 79\% of people planned to shop online in 2015. The poll used a convenience sample, so the results tell us little about the population of all adults. The poll used voluntary response, so the results tell us little about the population of all adults. The sample is too small to draw any conclusions. None of the previous answers is correct.

To analyze the survey results from FreezeFrame, let's break down the information provided and the implications of the survey method used.

1. **Survey Details**:
   - Total respondents: 45,000+
   - Percentage responding "yes" to shopping online: $$ 79\% $$

2. **Understanding the Survey Method**:
   - The survey was conducted through a voluntary response method, meaning that individuals chose to participate by clicking a response. This type of sampling can lead to bias because it may attract individuals with strong opinions (either positive or negative) about the question being asked.

3. **Evaluating the Options**:
   - **Option 1**: "About 79% of people planned to shop online in 2015." 
     - This statement is misleading because it implies that the survey results can be generalized to the entire population, which is not necessarily true due to the voluntary response method.
   
   - **Option 2**: "The poll used a convenience sample, so the results tell us little about the population of all adults."
     - This is partially true, but the term "convenience sample" is not entirely accurate here; it is more about voluntary response.

- **Option 3**: "The poll used voluntary response, so the results tell us little about the population of all adults."
     - This is a valid conclusion. Voluntary response surveys often do not accurately represent the broader population because they can be biased towards those who feel strongly about the issue.

- **Option 4**: "The sample is too small to draw any conclusions."
     - This is incorrect because 45,000+ respondents is a large sample size.

- **Option 5**: "None of the previous answers is correct."
     - This is not true since Option 3 is a valid conclusion.

4. **Conclusion**:
The most accurate conclusion based on the survey method and results is:

**The poll used voluntary response, so the results tell us little about the population of all adults.**

Thus, the correct answer is **Option 3**.
The survey likely used voluntary response, so its results may not accurately represent all adults.
