In a survey of 3098 adults aged 57 through 85 years, it was found that 80.2% of them used at least one prescription medication. Complete parts (a) through (c) below. a. How many of the 3098 subjects used at least one prescription medication? (Round to the nearest integer as needed.) b. Construct a 90% confidence interval estimate of the percentage of adults aged 57 through 85 years who use at least one prescription medication. % < p <% (Round to one decimal place as needed.) c. What do the results tell us about the proportion of college students who use at least one prescription medication? O A. The results tell us that, with 90% confidence, the probability that a college student uses at least one prescription medication is in the interval found in part (b). O B. The results tell us that, with 90% confidence, the true proportion of college students who use at least one prescription medication is in the interval found in part (b). O c. The results tell us that there is a 90% probability that the true proportion of college students who use at least one prescription medication is in the interval found in part (b). O D. The results tell us nothing about the proportion of college students who use at least one prescription medication.
