The mean of 6 distinct observations is 6.5 and their variance is10.25 .If 4 out of 6 observations are 2,4,5,7. Then remaining two observations are

The mean of 5 observations is 4.4 and variance is 8.24. If three of the five observations are 1,2, and 6 then remaining two observations are (i) 9, 16 (ii) 9, 4 (iii) 81, 16 (iv) 81, 4

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 :

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 of five observations is 4 and their variance is 5.2. If three of these observations are 1,2 and 6, then the other two are

The mean of five observation is 4 and their variance is 2.8. If three of these observations are 2, 2 and 5, then the other two are

The mean of 5 observations is 5 and their variance is 12.4. If three of the observations are 1,2 and 6, then the mean deviation from the mean of the data is

The mean of five observations is 5 and their variance is 9.20. If three of the given five observations are 1,3 and 8, then a ratio of other two observations is

The means of five observations is 4 and their variance is 5.2. If three of these observations are 1,2 and 6, then the other two are (a) 2 and 9 , (b) 3 and 8 , (c) 4 and 7 , (d) 5 and 6

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

The mean of 5 observations 1,2,6,x and y is 4.4 and their variance is 8.24 , then x+y is
