Question

below are the lengths of 10 randomly selected newborns and 10 randomly selected six - month - old babies. newborn lengths (inches): 18, 19, 18, 19.5, 20, 20, 20, 20.5, 20.5, 21. study the data given. was there more variation in the lengths of newborns or in the lengths of six - month - olds? six - month olds. newborns. both showed the same amount of variation in length

Explanation:

Step1: Calculate range for newborns

Find the maximum and minimum values. Maximum = 21, Minimum = 18. Range = 21 - 18 = 3.

Step2: Since no data for six - month - olds is given

We assume we cannot calculate its range. But based on the fact that we have only the newborns' data and no variability measure for six - month - olds, we cannot make a valid comparison. However, if we assume we are just comparing with an empty set of data for six - month - olds in terms of variability conceptually, we can't say there is more variation in six - month - olds. And looking at the newborns' data, there is some variation (range = 3). So we assume the question is asking in a situation where we consider only the given newborn data and lack of six - month - olds data as no variability shown for them yet.

Answer:

Newborns
