Question

the mean of 5 items is 200. later now, it was discovered that the two tems were misread 92 and8 instead of 192 and88. find the correct mean​

Answer 1

Answer:As the mean of 200 items is 50. So,

Total items= 200*50 = 10000.

Now,

Difference of items due to misread

= (192-92 )+ (88-8) = 100 + 80 = 180.

Then, Add 180 to the total value

i.e. 10000+180 = 10180.

So, Correct mean= 10180/200 = 50.9
