D) The mean birthweight is lower for those who survived.

Quizplus · Accepted Answer

The boxplot shows that the median birthweight for infants who survived SIRDS is higher than those who died. This means that the median birthweight is lower for those who died. Therefore, choice A is the correct answer. The boxplot does not provide information on the mean birthweights, so B and D are not correct. Additionally, the boxplot shows that there is overlap in the interquartile ranges for both groups, so it cannot be determined if the median birthweight is greater for those who survived (C).
