Question: Age of Death for SIDS Infants and Gender

In their paper “Maternal Cigarette Smoking and Oral Clefts: A Population-Based Study” in the American Journal of Public Health (1987) Khoury et al. present information about the ages at which infants died from SIDS. Is there evidence based upon their data to conclude that the age of death differs by gender?

Here are the ages of death (days) for the infants that died from SIDS in their study:

Females:
53 56 60 60 78 87 102 117 134 160 277

Males:

46 52 58 59 77 78 80 81 84 103 144

115 133 134 167 175

Conduct an appropriate test for determining if there is difference in the typical age at which female and male SIDS infants die. Summarize your findings. (5 pts.)
