Given the following data, find the weight that represents the 73rd percentile. Weights of Newborn Babies 8.2 6.6 5.6 6.4 7.9 7.1 6.5 6.0 7.8 8.0 6.8 8.8 9.3 7.7 8.8

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.
