1. The American Journal of Public Health (July 1995) published a study of the relationship between passive smoking and nasal allergies in Japanese female students. The study revealed that 80% of students from heavy-smoking families showed sign of nasal allergies on physical examinations. Consider a sample of 20 Japanese female students exposed daily to heavy smoking. What is the probability that fewer than 15 of the students will have nasal allergies? X<13 n=20, P=0.808 I =<15 a. b. What is the probability that more than 10 of the students will have nasal allergies? X > O c. What is the probability that exactly 10 of the students will have a nasal allergy?
