Answer 1

Answer:

8,9,11,14,15,17,20,22,25

the 10 observation of the median is=

(10/2) and( 10 /2+1)

so the median is = 15+17/2

=16

Step-by-step explanation:

i hope it help you

Answer 2

Given observations = 8,9, 11,14, 15,17, 18,20,22,25

No of observations =10 (even)

So,

(n/2)th obs =(10/2)th obs =5th obs =15

(n/2+1)th obs =5+1 =6th obs =17

Now,

• Median =(n/2) +(n/2+1) ÷2
• 5th obs +6th obs ÷2
• 15+17÷2
• 32/2
• =16
• Hence proved
