Suppose the mean of certain number of observation is 50 and the sum of all the observation is 450. Write down the number of observations.

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 2, 4 and 6, then the other two observations are

If the mean of six numbers is 41, then the sum of these numbers is

The mean and variance of 8 observations are 9 and 9.25 respectively. Suppose 6,7,10,12,12,and 13 are the first 6 observations. Let a and b be the remaining two observations. 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.

Decrease in atomic number is observed in :

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:

If the combined mean of the two group is 40/(3) and if the mean of one group with 10 observations is 15, then the mean of the other group with 8 observations is a) 46/(3) b) 35/(4) c) 45/(4) d) 41/(4)

Suppose that three numbers are in A.P.if the sum of the three numbers is 27 and the product of the numbers is 648, find the numbers
