Answer 1

A

58

Given that

the observations are

46,64,87,41,58,77,35,90,55,92,33

No. of observations(n)=11

Arrange the data in ascending order

33,35,41,46,55,58,64,77,87,90,92

Here observe that no. of observations are odd i.e., n=11

So median is

2

n+1

th term

Median=

2

n+1

th term=

2

11+1

th term

=6

th

term

=58

∴ Median=58

and

if

Here observe that no. of observations are odd i.e, n=1

so new median is

2

n+1

th term

=

2

n+1

th term=

2

11+1

th term

2

12

th term

=6

th

term (from (1))

=58

∴ New median=58.
