Correct Answer
C
Explanation
To find the mean and median of a set of numbers, we can follow these steps:1. Arrange the numbers in ascending order: 30, 31, 43, 44, 55, 56.2. Find the median, which is the middle value. In this case, the median is 44.3. Calculate the mean by summing all the numbers and dividing by the total count. In this case, the mean is (30 + 31 + 43 + 44 + 55 + 56) / 6 = 259 / 6 ≈ 43.17.To find the difference between the mean and median, we subtract the median from the mean:Difference = Mean - Median = 43.17 - 44 ≈ -0.33.Therefore, the mean of the given numbers is approximately 0.83 less than the median.
