1. Step-by-step explanation:

Given;

The average marks of 40 students in an examination =34

It was found that one student had been wrongly entered as 62 instead of 26.

The marks of students in an examination=40*34=1360

62-26=36

1360-36=1324

After correction of marks the mean =1324/40

=33.1

After correction of marks the mean is 33.1
