Answer:
Median is 110
Step-by-step explanation:
Let us write the data shown on the line plot
They are in ascending order as follows:
70,80,90,90,100,100,100,110,110,110,110,120,1200,120,120,130,130,140
There are 18 entries
The middle entries are 9 and 10
Hence median = average of 9th and 10th
= 110
