Confidence Interval for One Population Proportion In the article "Explaining an Unusual Allergy," appearing on the Everyday Health Network, Dr. A Feldweg 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, 40 of 400 randomly selected U.S. asthmatics were found to be allergic to sulfites. Find the 95% confidence interval for the proportion of all U.S. asthmatics who are allergic to sulfites: What is the standard error used to calculate this interval? Round to the 10,000ths place.
