Answer:
The correct option is B
Step-by-step explanation:
Arranging the data in an ascending manner, we have:
12, 18, 25, 26, 30, 31, 34
From the given data, we have:
Highest number = 34
Lower number = 12
Median = 26 (The middle number after arranging in order)
Upper quartile = 31 (The median of the upper half of the data)
Lower quartile = 18 (The median of the lower half of the data)
The plot is as follows:
