The accompanying table describes the random variable x the numbers of adults in groups of five who reported sleepwalking Complete parts a through d below Click the icon to view the table a Find the probability of getting exactly 4 sleepwalkers among 5 adults Type an integer or a decimal Do not round b Find the probability of getting 4 or more sleepwalkers among 5 adults Type an integer or a decimal Do not round 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 OA Since the probability of getting 4 sleepwalkers is the result from part a this is the relevant probability OB Since the probability of getting 5 sleepwalkers is less likely than getting 4 sleepwalkers the result from part a is the relevant probability OC Since the probability of getting fewer than 4 sleepwalkers is the complement of the result from part b this is the relevant probability OD 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 d Is 4 a significantly high number of 4 sleepwalkers among 5 adults Why or why not Use 0 05 as the threshold for a significant event OA Yes since the appropriate probability is greater than 0 05 it is a significantly high number B Yes since the appropriate probability is less than 0 05 it is a significantly high number OC No since the appropriate probability is greater than 0 05 it is not a significantly high number OD No since the appropriate probability is less than 0 05 it is not a significantly high number Probability Distribution f X Print X 0 1 2 3 4 5 P x 0 184 0 379 0 269 0 136 0 025 0 007 Done
