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, 22 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. Click here to view page 1 of the table of areas under the standard normal curve. Click here to view page 2 of the table of areas under the standard normal curve. The 90% confidence interval is from to (Round to three decimal places as needed.) Interpret the confidence interval. Choose the correct answer below. O A. With 90% confidence, the true proportion of all asthmatics in the country who are allergic to sulfites is within the bounds of the confidence interval found in the previous step. B. With 90% confidence, the sample proportion of all asthmatics who are allergic to sulfites will be within the bounds of the confidence interval found in the previous step. OC. There is a 90% probability that the true proportion of all asthmatics in the country who are allergic to sulfites is within the bounds of the confidence interval found in the previous step. OD. There is a 90% probability that the sample proportion of all asthmatics in the country who are allergic to sulfites will be within the bounds of the confidence
