Question

A library wants to expand their children’s book secton. The librarians surveyed 30 children by asking every 6th child that visited the library to figure out what genres were most popular.The children’s responses were: 12 liked fictons, 8 liked non-fictons, 4 liked science fiction,and 6 liked mystery. If the library expects 540 children to visit the library in a week, about how many children will check out a mystery book?

Answer 1

Explanation:

To estimate the number of children who will check out a mystery book, we can use the information provided in the survey.

Out of the 30 children surveyed, 6 liked mystery books. We can assume that this proportion holds true for the entire population of children visiting the library.

To estimate the number of children who will visit the library in a week, we are given that 540 children are expected to visit.

Here are the steps to estimate the number of children who will check out a mystery book:

1. Calculate the proportion of children who liked mystery books in the survey: 6/30 = 1/5.

2. Multiply this proportion by the estimated number of children visiting the library in a week:

(1/5) * 540 = 108.

Therefore, it is estimated that about 108 children will check out a mystery book.
