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

The mean of five numbers is 0 and their variance is 2. If three of those numbers are -1,1and2 , then the other two numbers are

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:

Find the variance for the observations 2,4,6,8, and 10 .

Mean of 10 observations is 50 and their standard deviation is 10. If each observation is subtracted by 5 and then divided by 4, then the new mean and standard deviation are a) 22.5, 2.5 b) 11.25, 2.5 c) 11.5, 2.5 d) 11,2.5

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

(b)Find mean deviatio from the mean for the observations -1,0,4.

If the mean of the numbers a, b, 8, 5, 10 is 6 and their variance is 6.8, then ab is equal to
