Answer 1

Answer:

D. There is one outlier, indicating an abnormally large number of books were rented out on that day.

Step-by-step explanation:

We have been given a data set that shows the number of books checked out from a library during the first two weeks of the month.

Our given data set is:  99, 29, 30, 42, 35, 36, 30, 35, 38, 43, 39, 40, 28, 31.

Let us arrange our given data points in ascending order.

28, 29, 30, 30, 31, 35, 35, 36, 38, 39, 40, 42, 43, 99.

We can see from our data set that it has one extreme large value outlier that is 99, which indicates that an abnormally large number of books were rented out on that day.    

Therefore, option D is the correct choice.
