From a random sample of potential voters in an upcoming election, 47% indicated they intended to vote for Candidate R. A 95 percent confidence interval was constructed from the sample, and the margin of error for the estimate was 5%. Which of the following is the best interpretation of the interval? A) We are 95% confident that the proportion who intend to vote for Candidate R from the random sample is between 42% and 52%. B) We are 95% confident that the proportion who intend to vote for Candidate R from the population is between 42% and 52%. C) We are 95% confident that the proportion who intend to vote for Candidate R from the random sample is 47%. D) We are 95% confident that the proportion who intend to vote for Candidate R from the population is 47%. E) We are confident that 95% of the population intend to vote for Candidate R.
Contingency Table
A contingency table can be defined as the visual representation of the relationship between two or more categorical variables that can be evaluated and registered. It is a categorical version of the scatterplot, which is used to investigate the linear relationship between two variables. A contingency table is indeed a type of frequency distribution table that displays two variables at the same time.
Binomial Distribution
Binomial is an algebraic expression of the sum or the difference of two terms. Before knowing about binomial distribution, we must know about the binomial theorem.

B) We are 95% confident that the proportion who intend to vote for Candidate R from the population is between 42% and 52%.
C) We are 95% confident that the proportion who intend to vote for Candidate R from the random sample is 47%.
D) We are 95% confident that the proportion who intend to vote for Candidate R from the population is 47%.
E) We are confident that 95% of the population intend to vote for Candidate R.
