In a survey of 1393 people, 936 people said they voted in a recent presidential election. Voting records show th eligible voters actually did vote. Given that 65% of eligible voters actually did vote, (a) find the probability that ar randomly selected voters, at least 936 actually did vote. (b) What do the results from part (a) suggest? (a) P(X≥ 936) = (Round to four decimal places as needed.) (b) What does the result from part (a) suggest? O A. Some people are being less than honest because P(x ≥ 936) is less than 5%.
