The accompanying table contains the results from experiments with a polygraph instrument. Find the probabilities of the events in parts (a) and (b) below. Are these events unlikely? a. Four of the test subjects are randomly selected with replaceme nt, and they all had true negative test results. b. Four of the test subjects are randomly selected without replacement, and they all had true neg alive test results. a Click on the icon to view the data table. a. The probability that all tourtest subjects had a tme negative test result when they are randomly seleded with replacement is D. (Round to three decimal places as needed.) ls such an event unlikely? O A. No, because the probability of the event is greater than 0.05. O B. No, because the probability of the event is less than 0.05. O C. Yes, because the probability of the event is greater than 0.05. O D. Yes, because the probability of the event is less than 0.05. b. The probability that all tourtest subjects had a true negative test result when they are randomly selected without replacement is :|. (Round to three decimal places as needed.) ls such an event unlikely? O A. No, because the probability of the event is less than 0.05. O B. Yes, because the probability of the event is less than 0.05. O C. No, because the probability of the event is greater than 0.05. O D. Yes, because the probability of the event is greater than 0.05
