Step 1 :The question is asking for the probability of getting exactly 4 sleepwalkers among 5 adults, the probability of getting 4 or more sleepwalkers among 5 adults, and which probability is relevant for determining whether 4 is a significantly high number of sleepwalkers among 5 adults.
Step 2 :Since we don't have the table, we can't calculate the probabilities directly. However, we can answer the third part of the question based on the given probabilities.
Step 3 :The question is asking which probability is relevant for determining whether 4 is a significantly high number of sleepwalkers among 5 adults. The answer should be the probability of getting 4 or more sleepwalkers, because we are interested in whether 4 is a significantly high number, so we need to consider the probability of getting 4 or more, not just exactly 4.
Step 4 :So, the answer should be A. Since the probability of getting 4 or more sleepwalkers is the probability of the given or more extreme result, the result from part (b) is the relevant probability.
Step 5 :\(\boxed{\text{A. Since the probability of getting 4 or more sleepwalkers is the probability of the given or more extreme result, the result from part (b) is the relevant probability.}}\)
