Based on the dotplot of the simulation results and the sample of 20 adults, which conclusion can be made?
O The actual probability that an adult cannot swim is
only 12%.
O It is clear that exactly 5 out of 20 adults will be
nonswimmers.
O If we continued to take more samples of 10 adults,
the center of the distribution would shift to 2.
O There is about a 12% chance of 2 or fewer
nonswimmers in a group of 20. This is not unusual
and is not convincing evidence that the true
probability that an adult cannot swim is less than
25%.
