The mean of 5 observations is 4.4 and their variance is 8.24.If three of the observations are 1,2 and 6,find the other two observations.

The mean and variance of 7 observations are 8 and 16 respectively. If five of the observations are '2,4,10,12,14'. Find the remaining two observations:

The mean and variance of 7 observations are 8 and 16 respectively . If five of the observations are 2,4,10,12,14 find the remaining two observations.

The variance of 20 observations is '5 .' If each observation is multiplied by 2, find the new variance of the resulting observations.

The mean of five observations is 4 and their variance is 5.2. If three of these observations are 2, 4 and 6, then the other two observations are
