In a survey of 1295 people, 905 people said they voted in a recent presidential election. Voting records show that 67% of eligible voters actually did vote. Given that 67% of eligible voters actually did vote, (a) find the probability that among 1295 randomly selected voters, at least 905 actually did vote. (b) What do the results from part (a) suggest? (a) P(X 2 905) = 0.0139 (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 905) is less than 5%. O B. Some people are being less than honest because P(x 2 905) is less than 5%. OC. Some people are being less than honest because P(x 2 905) is at least 1%. O D. People are being honest because the probability of P(x2 905) is at least 1%.
