Question

box plots represent the birth weights, in pounds, ofes born full term at a hospital during one week
complete the statements to compare the weights offemale babies with the weights of male babies
the median female birth weight is the
median male birth weight.
the range of female birth weight is the
range of male birth weight
which birth weight measure is the
genders?

Explanation:

• For the median: In a box - plot, the line inside the box represents the median. By observing the box - plots, the median of the female birth weight (line in the female box) is less than the median of the male birth weight (line in the male box).
• For the range: The range is calculated as \( \text{Range}=\text{Maximum}-\text{Minimum} \). By looking at the whiskers (the ends of the lines outside the box), for the female box - plot, the range is smaller than that of the male box - plot.
• For the measure that is the same: The inter - quartile range (IQR), which is \( Q3 - Q1 \) (the length of the box part of the box - plot), appears to be the same for both genders.

Answer:

1. less than
2. less than
3. inter - quartile range
