According to a past poll conducted of Lexington residents, 52% indicated support for a light rail public transportation system within the city of Lexington. The sample size was 400 Lexington residents. Calculate a confidence interval for this poll using a 95% confidence level (using the formula for proportions). What is the range in which we would expect to find the true proportion of Lexington residents who support a light rail system? We will assume that the proportion from the total population is equal to the sample.
