I. The geometric mean of 2,4,16 and 32 is a II. The strength of 7 colleges in a city are 385, 1748, 1343, 1935, 786, 2874 , 2108. Then the median strength is b. II. The algebric sum of the deviations of 20 observations measured from 30 is 2. The mean of these observations is c.

The algebraic sum of the deviations of a set of n values from their mean is (a) 0 (b) n-1 (c) n (d) n+1

If the sum of 10 observations is 95, then their mean is (a) 9.5 (b) 10 (c) 950 (d) 95

Prove that "The Algebraic Sum of deviations from Mean is zero".

If the sum of the deviations of 50 observations from 30 is 50, then the mean of these observations is

Sum of squares of deviation of 10 observations measured from 5 is 17 and sum of squares ofobservations is 170 then mean of observation is

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
