Polling suggests that 38% of the US adult population does not own a car. A random sample of 500 Americans will be taken. The sampling distribution of a sample proportion suggests that: (select all of the following which are correct) Select one or more:

A) 38% of the 500 Americans sampled will not own a car.

B) Across a large number of random samples, we should expect that, on average, 38% of the 500 Americans sampled will not own a car.

C) It is less likely for less than 36% of the 500 Americans sampled to not own a car than it is for more than 40% of the Americans sampled to not own a car.

D) It is more likely for more than 37% of the 500 Americans sampled to not own a car than it is for less than 38% of the Americans sampled to not own a car.

E) Since the 500 Americans are randomly sampled, we cannot make any kind of predictions about the resulting sample proportion.
