Question 39 of 50 • EHS Content Recovery - Probability and Statistics - Part D
A researcher for a polling organization used a random sample of 1,540 residents in a city to construct a 95 percent confidence interval for the proportion of voters who would vote for candidate Jones. The resulting confidence interval was 0.480 ± 0.025. What is the correct interpretation of the confidence interval?
Answer
A
A proportion of 0.455 and 0.505 of respondents think that Jones has a 95% chance to win.
B
If 95% of all the voters voted, then Jones would receive between 45.5% and 50.5% of the votes.
C
The polling organization can be 95% confident that the interval from 0.455 to 0.505 captures the proportion of all city voters who would vote for Jones.
D
If we repeatedly sampled voters from this city, taking samples of size 1,540, approximately 95% of those samples would have between 45.5% and 50.5% voting for Jones.
