Answer 1

Answer:

(B)

Step-by-step explanation:

The given set is:

10, 89, 80, 95, 85, 92, 90, 9, 99, 97, 96, 92, 91, 88.

We know that an Outlier is an observation which is quite different or far away from the rest of the given data set values.

From the above given data set, we can see that 9 and 10 are very far or different from the rest of the data set values which ranges between 80-99.

Thus, 9 and 10 are the outliers of the above given data set and are less than the rest of the given data values.

Therefore, There are two outliers, indicating very few books were rented out on those two days.

Hence, option B is correct.
