Answer 1

the acsending order is 144,145,147,148,149,150,152,155,160

the n = 9(its odd)

Answer 2

HELLO.......FRIEND!!

THE ANSWER IS HERE,

The heights of the students are

144 , 145 ,147 ,148 ,149 ,150 ,152 ,155 ,160

There are totally 9 observations. And 9 is a odd number. So

The median => (n+1)/2.

=> (9+1)/2

=> 10/2

=> 5th observation.

So, the median is 149.
