Find the indicated measure. (show work)
The median weights (in pounds) of 30 newborn babies are listed below:

1. Find the 16th percentile: P16

2. Find the 23rd percentile: P23

5.5, 5.7, 5.8, 5.9, 6.1, 6.1, 6.4, 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

1) if we have to find the 16th percentile then the formula will be = p/100 x (n + 1)

here p =16 and n = 30

so the percentile will be 16/100 * 31 = 4.96

2) for 23rd percentile

23/100*31 = 7.13
