There are three …Solution: The calculated arithmetic mean of 40 numbers is 38. Hence, the sum of these numbers = (38 × 40) = 1520. Thus, the actual sum of these numbers = [1520 – (Incorrect value) + (correct value)] Correct Mean = 1520 – 36 + 56. Correct Mean = 1540. Hence, the correct mean of the given numbers = 1540/40 = 38.5. 5.Example 8.18. The wages of the factory workers are assumed to be normally distributed with mean and variance 25.
