Answer:mean = 153/12; median =13
Step-by-step explanation:
mean = sum of observation/ no of observation
=4+6+8+9+10+12+14+15+16+18+20+21/12
=153/12
median
4,6,8,9,10,12,14,15,16,18,20,21
n=12, even
median =[(n/2)th +(n/2+1)th]term
= [(12/2)th +(12/2+1)th] term
= [ 6th + 7th ]/ 2 term
= 12+14/2
=26/2
=13
