View answer and explanation

Correct option: C

\frac{1}{3}\left( {2\;n + 1} \right)

Option C (

\frac{1}{3}\left( {2\;n + 1} \right)

) is correct because the weighted AM is calculated by dividing the sum of the products of the numbers and their weights by the sum of the weights.

\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
