A large state university finds that 82 of a random sample of 200 of its first-year students engage in binge drinking. Find a 90% confidence interval for the proportion of all first-year students at the state university who engage in binge drinking. Also find the margin of error. Round all of your answers to four decimal places. 90% Confidence Interval: ( [LL] , [UL] ) Margin of Error: [E]
