Given the following data, find the weight that represents the 53rd percentile.

Weights of Newborn Babies9.4 7.5 5.4 7.5 7.1

6.0 8.1 5.7 7.1 6.6

9.4 5.8 8.7 5.7 9.3

Step-by-step explanation:

Rearranging the weights in ascending order, it becomes

5.4, 5.7, 5.7, 5.8, 6.0, 6.6, 7.1, 7.1, 7.5, 7.5, 8.1, 8.7, 9.3, 9.4, 9.4

The formula for determining the percentile is expressed as

n = (P/100) N

Where

n represents the value of the given percentile

P represents the given percentile

N represents the number of items (weights)

From the information given, the number of items, n is 15

P = 53

Therefore,

n = (53/100) * 15

n = 7.95

n = 8

Therefore, the weight that represents the 53rd percentile is the 8th value. It becomes 7.1

53rd percentile is 7.1
