Answer:
8
Step-by-step explanation:
Arranging the data into the increasing order
5.6 6.0 6.4 6.5 6.6 6.8 7.1 7.7 7.8 7.9 8.0 8.2 8.8 8.8 9.3
73n/100=73*15/100=10.95 is not an integer
So, the 73rd percentile is
P73= weight of (73n/100)+1
P73= weight of observation (10+1)
P73=weight of 11th observation
P73=8.
The weight that represents the 73rd percentile is 8.
