Question
![In an article about unusual allergies, a doctor explained that allergy to sulfites is usually seen in patients with asthma.
The typical reaction is a sudden increase in asthma symptoms after eating a food containing sulfites. Studies are
performed to estimate the percentage of the nation's 10 million asthmatics who are allergic to sulfites. In one survey,
32 of 400 randomly selected asthmatics in the country were found to be allergic to sulfites. Find and interpret a 90%
confidence interval for the proportion, p, of all asthmatics in the country who are allergic to sulfites.
