(A)The margin of error for the given interval is 0.04.
(B)We can conclude that a majority of young adults drink coffee daily.
(C) There is a 95% probability that the true proportion of young adults that drink coffee is between 0.14 and 0.18.
(D)We can be 95% confident that the true proportion of young adults that drink coffee daily is between 0.14 and 0.18.
(E) If this procedure were to be repeated many times, 95% of the resulting confidence intervals will display that the true proportion of young adults that drink coffee daily is between 0.14 and 0.18.

Which of the following situations would most likely occur if a human-induced event caused the ocean water to become the same temperature around the world? deep ocean current circulation would increase salt distribution around the world's oceans. surface ocean current circulation would distribute heat around land masses at a faster rate. new, fresher water would float on top of dense salt water and limit thermohaline circulation. some land masses in the northern hemisphere would start to warm up over time, melting snow and ice. runoff of surface freshwaters and rainfall would no longer have an effect on the salinity of ocean waters.
