Standard deviation of 3, 5, 7 is

Standard deviation of 3, 4, 5 is

Standard deviation of 3, 5, 7, 9, 11, 13 is

If the standard deviation of a, b, c is sigma this standard deviation of 4a+7, 4b+7, 4c+7 will be of:

If variance of 1, 3, 5, 7, …….. 215 is A^(2) then standard deviation of 1, 5, 9, 13, …..429 in terms of A is :

If variance of 1, 3, 5, 7, …….. 215 is A^(2) then standard deviation of 1, 5, 9, 13, …..429 in terms of A is :

Standard deviation of 1, 2, 3, 4, 5 is 2. Then standard deviation of (-2), (-4), (-6), (-8), (-10) is

If the standard deviation of x, y, z is p then the standard deviation of 3x+5, 3y+5, 3z+5 is ___.

If the standard deviation of a data is 4.5 and if each value of the data is decreased by 5, then find the new standard deviation.
