In a survey of 1309 people, 825 people said they voted in a recent presidential election. Voting records show that 60% of eligible voters actually did vote. Given that 60% of eligible voters actually did vote,
(a) find the probability that among 1309 randomly selected voters, at least 825 actually did vote.
(b) What do the results from part (a) suggest?
(a) P(X ≥ 825) = ………..
(Round to four decimal places as needed.)
(b) What does the result from part (a) suggest?
A. Some people are being less than honest because P(x ≥ 825) is at least 1%.
B. Some people are being less than honest because P(x ≥ 825) is less than 5%.
C. People are being honest because the probability of P(x ≥ 825) is less than 5%.
D. People are being honest because the probability of P(x ≥ 825) is at least 1%.
a). P(X>=825)= 0.0119
b). Correct answer is option C
Result from part (a) suggest that people are being honest because the probability of P(X>=825) is less than 5%
