Answer 2

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
