Suppose values taken by a variable

x

are such that

a \leq x_i \leq b

, where

x_i

denotes the value of

x

in the

i

th case for

i=1,2,3, \ldots, n

. Then,

View answer and explanation

Correct option: D

(b-a)^2 \geq \operatorname{Var}(x)

Option D (

(b-a)^2 \geq \operatorname{{Var}}(x)

) is correct because the variance is always less than or equal to the square of the range.

If the mean of a set of observations

{x_1},{x_2}, \ldots ,{x_n}

\bar X,

then the mean of the observations

{x_i} + 2\;i;i = 1,\;2, \ldots ,n

is The sum of 10 items is 12 and sum of their squares is 18 , then standard deviation will be In a family, there are 8 men, 7 women and 5 children whose mean ages separately are respectively 24,20 and 6 years. The mean age of the family is The mean and variance of seven observations are 8 and 16, respectively. If 5 of the observations are 2, 4, 10, 12, 14, then the product of the remaining two observations is

1,3,5, x, y

are 5 observations. Mean of these observations is 5 and variance is 8. Sum of the cubes of the two missing number equals: If s.d. of a set of observations is 8 and if each observation is divided by

-2,

the s.d. of the new set of observations will be
