Question

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.

a. no, since the appropriate probability is greater than 0.05, it is not a significantly high number

b. yes, since the appropriate probability is less than 0.05, it is a significantly high number

c. yes, since the appropriate probability is greater than 0.05, it is a significantly high number

d. no, since the appropriate probability is less than 0.05, it is not a significantly high number

Explanation:

A significantly high number for a probability - based event is determined by comparing the probability of the event to a threshold (here 0.05). If the probability of having 4 sleepwalkers among 5 adults is less than 0.05, it is considered significantly high. If it's greater than 0.05, it's not.

Answer:

B. Yes, since the appropriate probability is less than 0.05, it is a significantly high number
