Question

The data set below shows the number of homework assignments required in math classes for a month: 22 23 23 21 18 4 17 15 23 20 24 15 25 16 Which of the following statements is true based on the data set?
a. There is one outlier that indicates an unusually large number of assignments required in that class.b. There is one outlier that indicates an unusually small number of assignments required in that class.c. There are two outliers that indicate an unusually large number of assignments required in those two classes.d. There are two outliers that indicate an unusually small number of assignments required in those two classes.

Answer 1

Answer:

b. There is one outlier that indicates an unusually small number of assignments required in that class.

Step-by-step explanation:

Outlier is the point which is very different or far away from the other points and this point greatly affect our result.

In the given data 4 is the outlier because it has large distance from other points present in the data. Since all other points are in between 15 to 23.

Also, 4 is smaller than other points of data.

Hence, There is one outlier that indicates an unusually small number of assignments required in that class.

Thus, Option B is  only correct.
