Answer:
P16= 6.1
Explanation:
We have given:
The weights (in pounds) of 30 newborn babies are listed below. Find p16. 5.5 5.7 5.8 6.0 6.1 6.1 6.3 6.4 6.5 6.6 6.7 6.7 6.7 6.9 7.0 7.0 7.0 7.1 7.2 7.2 7.4 7.5 7.7 7.7 7.8 8.0 8.1 8.1 8.3 8.7
To find the P(16) first we have to sort out our data.
Our data is already in sorted form.
Now apply the formula to find the P16 which means 16th percentile.
P(n)/100
where P= 16
and n = 30
=16(30)/100
=480/100
= 4.8 ≈ 5
If you round it to 5 you get P16 = 6.1....
