Detailed Solution
Download Solution PDFGiven:
Average weight of 25 women = 65.6 kg
Weight of one woman was read as 60 kg instead of 70 kg
Formula Used:
Actual Sum of weights = Calculated Sum of weights - Incorrect weight + Correct weight
Actual Average weight = Actual Sum of weights / Number of women
Calculations:
Calculated Sum of weights = Average weight × Number of women
Calculated Sum of weights = 65.6 × 25
Calculated Sum of weights = 1640 kg
Actual Sum of weights = 1640 - 60 + 70
Actual Sum of weights = 1650 kg
Actual Average weight = 1650 / 25
Actual Average weight = 66 kg
∴ The actual average weight of the group of 25 women is 66 kg
