Daisy knows that $\hat{p}=0.07$. What does Daisy know?
The hat tells me that the sample had a proportion of $7 \%$
The hat tells me that the population has a proportion of $7 \%$
The parameter is $7 \%$
None of the above
Answer
\(\boxed{\text{'The hat tells me that the sample had a proportion of 7 \%'}}\)
Step 1 ：The symbol $\hat{p}$ is often used in statistics to represent the sample proportion. In this case, Daisy knows that the sample had a proportion of $7 \%$. This does not necessarily mean that the population also has a proportion of $7 \%$, as the sample is just a subset of the population and may not perfectly represent it.
Step 2 ：Therefore, the correct answer is 'The hat tells me that the sample had a proportion of $7 \%$'.
Step 3 ：\(\boxed{\text{'The hat tells me that the sample had a proportion of 7 \%'}}\)
