The mean of the data set comprising of 16 observation is 16. If one of the observation valued 16 is deleted and three new observations 3, 4, & 5 are added to the data. Then the mean of resultant data is

The mean of the data set comprising of 16 observations is 16. If one of the observation valued 16 is deleted and three new observations valued 3, 4 and 5 are added to the data, then the mean of the resultant data, is : (1) 16.8 (2) 16.0 (3) 15.8 (4) 14.0

The mean of 16 observations is 16 . If one observation 16 is deleted and three observations 5 , 5 and 6 are included , then find the mean of the final observations .

If the mean of 15 observations is 16, find the sum of the 15 observations.

The mean of a data set consisting of 20 observation is 40. If one observation 53 was wrongly recorded as 33, then the correct mean will be

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 10 observations is 12. If mean of first 6 observations is 13. Find the mean of remaining 4 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 10 observations is 15. If one observation 15 is added, then the new mean is (a) 16 (b) 11 (c) 10 (d) 15

Given the that variance of 50 observations is 18. If each of the 50 observations is increased by 2, then variance of new data is

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 :
