Answer 1

Answer:

3

for doubt what's app 9467169711

Answer 2

1,3,5,7,9,11,13,15,17

Median =9

So, the lower half from the median = first quartile =1,3,5,7

Median of the first quartile =  

2

3+5

​  

=4

Similarly, the upper half from the median = third quartile =11,13,15,17

Median of the third quartile =  

2

13+15

​  

=14

IQR = third quartile − first quartile

=14−4=10.
