The mean of 6 distinct observations is 6.5 and their variance is10.25 .If 4 out of 6 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 :

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

The mean of 25 observation is 36 . Out of these observations, if the mean of first 13 observations is 32 and that of the last 13 observations is 40 , the 13th observation is
