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
