Answer:
Step-by-step explanation:firstly you need to arrange the numbers from smaller to bigger:3,4,9,10,12,15,17,27,47,48
n=10 (even )
mean: sum of all observation÷total no.of observation
=3+4+9+10+12+15+17+27+47+48÷10
=19.2
medium:(n÷2)th observation +(n+1÷2 ) th observation(whole thing divided by 2)
=5th observation + 6th observation ÷2
=12+15÷2
=27÷2
=13.5
