In a past presidential election, 39,885,048. people voted for Candidate A; 39,660,675 Candidate B; and 193,670 for third-party candidates.
a. What percentage of voters chose Candidate A? Find the % of voters who chose Candidate A Answer _____%
b. Would it be appropriate to find a confidence interval of voters choosing Candidate A? (Answer is A,B,C or D)
A.Yes, it is appropriate to find a confidence interval because the proportion is a sample proportion and the conditions for the Central Limit Theorem are met.
B.No, it is not appropriate to find a confidence interval because there are three possible outcomes for each observation.
C.No, it is not appropriate to find a confidence interval because the proportion is a population proportion.
D.No, it is not appropriate to find a confidence interval because the conditions for the Central Limit Theorem are met
Homework Answers
a) Percentage of voters chose Candidate A = 39885048 / (39885048 + 39660675 + 193670) = 0.5002 = 50.02%
b) No, it is not appropriate to find a confidence interval because the proportion is a population proportion. Option C is correct.
