Question Help ! bes the random variable x, the numbers of adults in groups of five who roported sloepwalking. Complete parts (a) through (d) below. EEB 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 i Probability Distribution for x (Type an integer or a decimal. Do not round.) c. Which probability 0 A. Since the probability of getting 4 sleepwalkers is the result from part (a), this is th relevant probability. O B. Since the probability of getting 5 sleepwalkers includes getting 4 sleepwalkers, the result from part (b) is the relevant probablily x P(x) is relevant for determining whether 4 is a significanty high number of sleepwalkers among 5 aduls: the result from part (a) 0.159 0.410 20.272 0.125 0.027 0,007 or part (b)? c. Since the probability of getting fewer than 4 sleepwalkers is the complement of the result from part (b), this is the relevant probability D Since the probability of getting 5 sleepwakers is less likely than getting 4 sleepwalkers, the result rom part ea s the rele art prb abilty 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 even n A Yas since the annronriate nrmhability is less than 0.05 it is a sinnificanty hish numhen Print Done Click to select your answerfs).

Explanation / Answer

Result:

a). P=0.027

b). P= 0.027+0.007 = 0.034

c).

A. since probability of getting 4 sleepwalkers is the result from part(a), this is the relevant probability.

d).

B. No, since the appropriate probability is less than 0.05, it is not a significant high number.
