Question
The mean of 36 numbers was found as 42. Later on, it was
determined that a number 47 was misread as 41. Find the correct mean of the given numbers (rounded off to two places of decimal).Solution
ATQ, The original sum of the numbers was 42×36 =1512. The number 47 was misread as 41, so the sum is 6 less than it should be. To correct it, add 6 to the sum: 1512+6 = 1518. Divide the corrected sum by 36 to find the new mean: 1518÷36 = 42.17. So, the correct mean is 42.17.
