Answer 2

Answer: (a) 27.5

(b) 21

(c) 61.5

Step-by-step explanation:

(a) we know that

the observation is even no. which is 10

= (nth observation /2)+(nth observation/2+1)/ 2

=(10/2)+(10/2+1)/2

=5th +6th / 2

=27+28=55/2=27.5

(b) we know that

the observation is odd no. which is 9

=(nth observation +1/2)

=(9+1/2)

=10/2=5th observation= 21

(c) we know that

the observation is even no. which 10

=(nth observation/2)+( nth observation/2+1)

=(10/2)+(10/2+1)= 5th +6th /2= 60+63/2

=123/2=61.5
