Your stats teacher wants to estimate the proportion of people at New Jersey beaches who are wearing sunscreen with a SPF of 30 or more. If they wanted to devote a whole summer to taking 500 different random samples of 100 people each time and making 500 different 95% confidence intervals, about how many of those confidence intervals would be expected to actually contain the true, unknown population proportion of people at New Jersey beaches who wear factor 30+ sunscreen, and about how many intervals are expected to “miss” the parameter?
