Question

The mean of 10 observations was calculated as 40. It was detected on rechecking that the value of 40 was wrongly copied as 10. Find the correct mean.

Answer 1

Answer:

HERE IS YOUR ANSWER MATE

Step-by-step explanation:

Observations= 10

Mean = 40

= 40*10

=400

If the observation 40 was wrongly copied as 10 then

Correct Observation= 40-10

= 30

Sum of correct Observations = 400+30

Correct mean = 430/10

= 43

Hence, the correct mean was 43.
