This question here says, each year in the us about 1 ,600 infants die from sudden infant death syndrome, that is sids, which is defined as the sudden death of an infant less than one year of age that cannot be explained after a thorough investigation is conducted.
00:19
One of the earliest research studies on this syndrome was conducted by taylor et al in 1996.
00:26
In this study, researchers collected data on the sleep position of 47 infants who had died of sids, and compared them to the sleep position of 142 randomly selected infants in the same county who didn't die from sids.
00:42
Among the sids group, 27 infants slept in the prone position, it means on their stomach, and among the non -sids groups, 35 infants slept in the prone position.
00:53
So in this case, they're asking us to get a two by two table.
00:57
So in this case, you're gonna have here prone position, that is the risk factor, and you have here no prone position, and you have here sids, and here you have no sids.
01:23
In this case, again, it says that you have 47 infants who died of sids, it means you have here 47 who died from sids here, and compared them to the sleep position of 142 randomly selected infants in the same country who didn't die from sids...
