For a bivariate distribution

(x, y)

if

\sum x=50, \sum y=60, \sum x y=350, \bar{x}=5, \bar{y}=6 .

Variance of

x

is 4 , variance of

y

is 9 , then

r_{x y}

equals

View answer and explanation

Correct option: C

\frac{5}{6}

Option C (

\frac{5}{6}

) is correct because it is the calculated correlation coefficient using the given data.

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
