" If "int_(i=1)^(18)(x_(1)-8)=9and(1)/(2)(x_(1)-8)^(2)=

If sum_(i=1)^(18)(x_(i)-8)=9 and sum_(i=1)^(18)(x_(i)-8)^(2)=45 then the standard deviation of x_(1),x_(2),...,x_(18) is

If sum_(i=1)^(18)(x_(i)-8)=9 and sum_(i=1)^(18)(x_(i)-8)^(2)=45 then find the standard deviation of x_1 , x_2, ....,x_(18)

STATEMENT-1: If sum_(i=1)^(9)(x_(i)-8)=9 and sum_(i=1)^(9)(x_(i)-8)^(2)=45 then s.D.~ of~ x_(1),x_(2),.....,x_(9), is 2. STATEMENT- 2: S.D.is independent of change of origin.

If x_(1), x_(2), "…......." x_(18) are observation such that sum_(j=1)^(18)(x_(j) -8) = 9 and sum_(j=1)^(18)(x_(j) -8)^(2) = 45 , then the standard deviation of these observations is

If x_(1), x_(2), "…......." x_(18) are observation such that sum_(j=1)^(18)(x_(j) -8) = 9 and sum_(j=1)^(18)(x_(j) -8)^(2) = 45 , then the standard deviation of these observations is

If sum_(i=1)^(18)(x_(i) - 8) = 9 and sum_(i=1)^(18)(x_(i) - 8)^(2) = 45 then find the standard deviation of x_(1), x_(2),….x_(18)
