Solution) Middle Ear Effusion in Breast-Fed and Bottle-Fed Infants A common symptom of otitus media in young

Question: Middle Ear Effusion in Breast-Fed and Bottle-Fed Infants
A common symptom of otitus media in young children in the prolonged presence of fluid in the middle ear, known a middle-ear effusion. The presence of fluid may result in termporary hearing loss and interfere with normal learning skills in the first two years of life. One hypothesis is that babies who are breast-fed for at least 1 month build up some immunity against the effects of the disease and have less prolonged effusion than do bottle-fed babies. A small study of 24 pairs of babies is set up, where the babies are matched on a one-to-one basis according to age, sex, socioeconomic status, and type of medications taken. One member of the matched pair is a breast-fed baby, and other member is a bottle fed baby. The outcome variable is the duration of middle-ear effusion after the first episode of otitus media. The results are shown below.

Do these data provide evidence that breast-fed babies have shorter durations of effusion when compared to bottle-fed babies that are the same age, sex, socioeconomic status, and on the same medications? Note: You have analyzed these data previously, however on could argue that your previous analysis was deficient in some respects. These data are in the file Ear Effusion.JMP.

What test procedure do you think should be used for analyzing these data? Explain
your choice, conduct the analysis, and summarize your findings. (5 pts.)
