Eduncle Best Answer
Check by options
Option (1) majority of the scholars published 4 papers = 60%
and scholars published more than 4 papers = 40%
which is not the majority
So option (1) is incorrect.
Option (2) is saying that 60% of the scholars published at least 2 papers if you will see the 60% so here at least 2 papers means 2 or more than 2 papers if we will see 60% of students will have published 2 papers or more than that
So option (2) is correct.
Option (3) 80% of the scholars published at least 6 papers.
See the graph 80% of the scholars have published only 6 papers or less than that so option (3) is incorrect.
Option (4) draw a horizontal line between 20% and 40% and then a vertical line we will see that 30% of the scholars have published at least 1 paper
So option (4) is incorrect.
