Fantasy
10
Literature

Which explains whether or not Sahira’s sample is representative?
No, it is not representative because literature books were chosen much more often than the other types.
Yes, it is representative because each type of book was chosen a unique number of times.
Yes, it is representative because each type of book was represented in the approximate proportion that exists in the library.
Yes, it is representative because each type of book was selected as part of the sample.

Answer 1

Answer: C: Yes, it is representative because each type of book was represented in the approximate proportion that exists in the library.

Answer 2

C: Yes, it is representative because each type of book was represented in the approximate proportion that exists in the library.

Explanation:

Given is a chart, showing the distribution of the number of books in a library.

Also given that Sahira chooses a random sample from the library and records the type of books in the chart below.

Sahira's sample can be said to be representative because given that books are taken at random. So just because literacy books were more we cannot say it is not representative II option is not right, because each book was not chosen uniquely, just random books were drawn

Last option c is right, because each book selected represents the sample from population of full library books.
