Given the following data, find the weight that represents the 22nd percentile. Weights of Newborn Babies 7.87.95.85.85.7 5.66.98.77.97.8 7.56.77.58.85.7

Step-by-step explanation:

Given the data: 7.8 7.9 5.8 5.8 5.7 5.6 6.9 8.7 7.9 7.8 7.5 6.7 7.5 8.8 5.7

Rearranged data: 5.6, 5.7, 5.7, 5.8, 5.8, 6.7, 6.9, 7.5, 7.5, 7.8, 7.8, 7.9, 7.9, 8.7, 8.8

The 22nd percentile :

Percentile (i) = (P / 100) * n

Where i = rank, n = Same size ; P = pw cwntile.

P = 22 ; n = 15

i = (22/100) * 15

i = 3.3 rd

The 22nd percentile is equivalent to 4th data in the ordered set = 5.

good luck on your studies! : )

you didn't post any answer choices, so its not 100% clear what your teacher is looking for

however, log(15/7) is equivalent to log(15) - log(7)

i'm using the rule log(x/y) = log(x) - log(y)
