Question

The mean of 1,7,5,3,4 and 4 is "a".The observations 3,2,4,2,3,3 and "a" have median 'b'. find a and b​

Answer 1

Answer:

Mean =m=

6

1+7+5+3+4+4

=

6

24

=4

Now mean of 3,2,4,2,3,3 and p is (m−1)=(4−1)=3

∴

7

3+2+4+2+3+3+p

=3

⇒

7

17+p

=3⇒17+p=21⇒p=4

∴ The observations are 3,2,4,2,3,3 and 4.

Arranged in ascending order, the numbers are 2,2,3,3,3,4,4.

Median =(

2

7+1

)

th

value=4

th

value=3
