Pren recorded this data set, which contains an outlier. 204, 216, 111, 224, 230, 211, 210, 198, 200, 218 What numbers represent
melamori03 [73]

Answer:

The correct option is D.

Step-by-step explanation:

The given data is

204, 216, 111, 224, 230, 211, 210, 198, 200, 218

Arrange the data in ascending order,

111, 198, 200, 204, 210, 211, 216, 218, 224, 230

The range is the difference between maximum value and minimum value.

Range=\text{upper limit}-\text{lower limit}

Range=230-111=119

Divide the data it two equal parts.

(111, 198, 200, 204, 210), (211, 216, 218, 224, 230)

Now divide the each in two equal parts.

(111, 198), 200, (204, 210), (211, 216), 218, (224, 230)

The mid value of first part is 200 and the mid value of second part is 218.

\text{lower quartile}=Q_1=200

\text{Upper quartile}=Q_3=218

Therefore option D is correct.
