when 274 college students are randomly selected and surveyed, it is found that 123 own a car. find a 99% confidence interval for the true proportion of all college students who own a car.
---------------
Sample proportion:: 123/274 = 0.45
----
ME = 2.5758*sqrt[0.45*0.55/274] = 0.077
-------------
99% CI 0.45-0.077 < p < 0.45+0.077
