Given that mean of 8 observations is 20
Let the values be x
1
,x
2
,...,x
8
Given that one value is 62
Let x
8
=62
Therefore,
8
x
1
+x
2
+...+62
=20
⟹x
1
+x
2
+....+x
7
+62=160
⟹x
1
+x
2
+...+x
7
=98 ————(1)
Given that 62 is misread and the correct mean is 15.5
Therefore, the correct mean is 15.5=
8
x
1
+x
2
+...+x
8
⟹x

+x
2

=15.5×8=124
⟹98+x

=124
⟹x

=124−98=26
