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.
E 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
relevant for determining whether 4 is a significantly high number of sleepwalkers among 5 adults: the result from part (a) or part (b)?
O A. Since the probability of getting 5 sleepwalkers is less likely than getting 4 sleepwalkers, the result from part (a) is the relevant probability.
O B. Since the probability of getting 4 sleepwalkers is the result from part (a), this is the relevant probability.
O C. Since the probability of getting fewer than
sleepwalkers is the complement of the result from part (b), this is the relevant probability.
O D. Since the probability of getting 5 sleepwalkers includes getting 4 sleepwalkers, the result from part (b) is the relevant probability.
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.
O A. Yes, since the appropriate probability is less than 0.05, it is a significantly high number.
O B. No, since the appropriate probability is less than 0.05, it is not a significantly high number.
Oc. Yes, since the appropriate probability is greater than 0.05, it is a significantly high number.
O D. No, since the appropriate probability is greater than 0.05, it is not a significantly high number.
