Question:medium
The mean and variance of 10 observations are 9 and 34.2, respectively. If 8 of these observations are
\( 2, 3, 5, 10, 11, 13, 15, 21 \), then the mean deviation about the median of all the 10 observations is:

Show Hint
For problems involving missing observations, always use the mean to find the sum and variance to find squared deviations.
