Mrs. liang, the librarian, wants to compare the numbers of patrons who prefer e-books to paperback books. she decides to take a poll of every third adult with a child who arrives at the library for one of the four reading groups: toddlers, preschoolers, primary grades, and upper elementary. which statement is true about her method of data collection? a) it is not balanced because it is less likely to include teens, young adults, and senior citizens in the patron population b) it is balanced because she is polling four different reading groups, which include all types of people

The appropriate description is A).

Mrs. Liang will be sampling the patron population with children who use reading groups. Unless that is the entire patron population, which we suspect it is not, her sampling method will be unrepresentative of the patron population as a whole.

You must include all choices, because you did not include the choices there were only two options available causing to answer your question incorrectly, all the options are as follows: A) It is balanced because she is including parents with children of all ages so she will get a greater age range.

B) It is not balanced because it is less likely to include teens, young adults, and senior citizens in the patron population.

C)It is not balanced because she only surveyed the adults and not the young children.

D)It is balanced because she is polling four different reading groups, which include all types of people.

Sorry but I don't know the correct answer to this because you gave me A, and that is clearly incorrect.

i think the amount would be $140.62
