Answer:
The correct option is 2.
Step-by-step explanation:
The given data set is
22, 23, 23, 21, 18, 4, 17, 15, 23, 20, 24, 15, 25, 16
Arrange the data is ascending order.
4, 15, 15, 16, 17, 18, 20, 21, 22, 23, 23, 23, 24, 25
Divide the data in 4 equal parts.
(4, 15, 15), 16, (17, 18, 20), (21, 22, 23), 23, (23, 24, 25)
Now, we can say that
The interquartile range of the data set is
If the data lie in the interval , then the data set has not outliers.
All the data lie in the interval [5.5,33.5] except 4. So, 4 is an outlier of the given data.
There is one outlier that indicates an unusually small number of assignments required in that class. Therefore the correct option is 2.
