OPTIONS:
A. The interquartile range is 7, and the range is 17.
B. The interquartile range is 7, and the range is 11.
C. The interquartile range is 2.75, and the range is 17.
D. The interquartile range is 2.75, and the range is 11.
Answer:
B. The interquartile range is 7, and the range is 11.
Step-by-step explanation:
From the dot plot display given in the attachment, we can find out the range and interquartile range of the data represented.
The range is the difference between the maximum value and the minimum value.
Min = 6
Max = 17
Range = 17 - 6 = 11
Interquartile range = Q3 - Q1
Q1 falls within the data value, 6.
Q3 falls within the data value 13.
Interquartile range = 13 - 6 = 7.
The statement that is true about the data represented is: "The interquartile range is 7, and the range is 11."
