In a survey of 1293 people, 953 people said they voted in a recent presidential election. Voting records show that 71% of eligible voters actually did vote. Given that 71% of eligible voters actually did vote, (a) find the probability that among 1293randomly selected voters, at least 953 actually did vote. (b) What do the results from part (a) suggest?(a) P(X2 953) =(Round to four decimal places as needed.)(b) What does the result from part (a) suggest?A. People are being honest because the probability of P(x2 953) is less than 5%.B. People are being honest because the probability of P(x2 953) is at least 1%.C. Some people are being less than honest because P(x2953) is less than 5%.D. Some people are being less than honest because P(x2953) is at least 1%.

Based on a survey, assume that 33% of consumers are comfortable having drones deliver their purchases. Suppose we want to find the probability that when six consumers are randomly selected, exactly three of them are comfortable with the drones. What is wrong with using the multiplication rule to find the probability of getting three consumers comfortable with drones followed by three consumers not comfortable, as in this calculation: (0.33)(0.33)(0.33)(0.67)(0.67)(0.67) = 0.0108? Choose the correct answer below. A. The event that a consumer is comfortable with drones is not mutually exclusive with the event that a consumer is not comfortable with drones. B. The probability of the second consumer being comfortable with drones cannot be treated as being independent of the probability of the first consumer being comfortable with drones. O C. There are other arrangements consisting of three consumers who are comfortable and three who are not. The probabilities corresponding to those other…
