In a survey of 1167 people, 860 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 1167 randomly selected voters, at least 860 actually did vote. (b) What do the results from part (a) suggest? (a) P(X 2 860) = | |(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(x2 860) is at least 1%. O B. People are being honest because the probability of P(x 2 860) is at least 1%. OC. Some people are being less than honest because P(x2 860) is less than 5%. O D. People are being honest because the probability of P(x2 860) is less than 5%.

Transcribed Image Text:In a survey of 1167 people, 860 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 1167 randomly selected voters, at least 860 actually did vote. (b) What do the results from
part (a) suggest?
(a) P(X 2 860) = |
|(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(x2 860) is at least 1%.
O B. People are being honest because the probability of P(x 2 860) is at least 1%.
OC. Some people are being less than honest because P(x2 860) is less than 5%.
O D. People are being honest because the probability of P(x2 860) is less than 5%.
