Question

c. which probability is relevant for determining whether 4 is a significantly high number of sleepwalkers among 5 adults the result from part (a) or part (b)?
a. since the probability of getting 5 sleepwalkers is less likely than getting 4 sleepwalkers, the result from part (a) is the relevant probability
b. since the probability of getting fewer than 4 sleepwalkers is the complement of the result from part (b), this is the relevant probability.
c. 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
d. since the probability of getting 4 sleepwalkers is the result from part (a), this is the relevant probability

Explanation:

To determine if 4 is a significantly high number of sleep - walkers among 5 adults, we consider the probability of getting 4 or more sleep - walkers. This is because significant high values are determined by the probability of the given or more extreme results. The result from part (b) gives the probability of getting 4 or more sleep - walkers.

Answer:

C. 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.
