1.Q1=1/4(n+1)
Q1=1/4(11+1)
Q1=1/4(12)
Q1=12/4
Q1=3
hahanapin Mo ung pangatlo dun SA data
final answer is Q1=10
2.D5=5/10(n+1)
D5=5/10(11+1)
D5=5/10(12)
D5=60/10
D5=6th element
D5=11
3.D7=7/10(n+1)
D7=7/10(11+1)
D7=7/10(12)
D7=84/10
D7=8.4 ung rules n sinabi is if NASA right side sya Ng data is round down ung sagot.8.4 maging 8 nlng sya
D7=8 round down
D7=12
4.P45=45/100(n+1)
P45=45/100(11+1)
P45=45/100(12)
P45=540/100
P45=5.4
P45=11
5.P80=80/100(n+1)
P80=80/100(11+1)
P80=80/100(12)
P80=960/100
P80=9.6
P80=13
