If standard deviation of variate `x_i` is 10, thenvariance of the variate `(50 +5x_i)` will be

The standard deviation of variate x_i is ?. Then standard deviation of the variate (ax_i+b)/c where a, b, c are constants is- (a) (a/c)sigma (b) |a/c| sigma (c) (a^2/c^2)sigma (d) Non of these

The standard deviation of variate x_i is σ. Then standard deviation of the variate (ax_i+b)/c where a, b, c are constants is- (a) (a/c)sigma (b) |a/c| sigma (c) (a^2/c^2)sigma (d) Non of these

The standard deviation of a variate x is sigma The standard deviation of the variable (aX+b)/c : a,b c, are constants, is

The standard deviationof a variable x is 10.Then the standard deviation of 50+5x is :

If standard deviation of a given data is 5 and mean is 50 then coefficient of variation (C.V) is equal to

If standard deviation of a given data is 5 and mean is 50 then coefficient of variation (C.V) is equal to a)100 b)0 c)1 d) 10

If standard deviation of a given data is 5 and mean is 50 then coefficient of variation (C.V) is equal to A) 100 B) 0 C) 1 D) 10
