A lоcаl news stаtiоn is interested in the prоportion of locаl residents that regularly get their news source from them rather than on the internet. A researcher randomly selects 170 residents, and found that 45 use the local news station for their news source. (Round to 3 decimal places.) a. Calculate a 99% confidence interval for the proportion of all local residents that use the local news station for their news source (input your interval as "(a, b)", where a is the lower limit and b is the upper limit of the interval) [a] b. Interpret the interval from part a (write out a sentence and be specific): We are 95% confident that [b] c. How many local residents need to be sampled in order to estimate the proportion to within 2% with 99% confidence? [c]
