It is true about Marcy's survey that she wants to study all visitors of the library and due to this, her sample is not representative.
<h3>What does Marcy want to study?</h3>
Marcy's study focuses on determining the type of books that visitors prefer to borrow. Based on this, Marcy is studying the preferences of all the visitors to the library.
<h3>How was the sample Marcy selected?</h3>
The sample selected is not representative because she is only considering those that go to the children's room on a specific day and time of the week rather than all the visitors.
Based on this, it can be concluded her population is all visitors and the sample is not representative.
