![Pediatrics, Otolaryngology
Otitis media is a disease that occurs frequently in the first
few years of life and is one of the most common reasons
for physician visits after the routine checkup. A study was
conducted to assess the frequency of otitis media in the
general population in the first year of life. Table 4.16 gives
the number of infants of 2500 infants who were first seen at
birth who remained disease-free by the end of the ith month
of life, i = 0, 1, . . . , 12. (Assume no infants have been lost
to follow-up.)

more episodes of otitis media by the end of the sixth month

more episodes of otitis media by the end of the ninth month
of life given that no episodes have been observed by the
