Answer:
B. There is 85% confidence that the proportion of the adult citizens of the nation that dreaded Valentine's Day is between 0.227 and 0.273
Step-by-step explanation:
The confidence level means the confidence that we have that the true mean is in the interval calculated.
The margin of error represents the range of values below and above the sample statistic in a confidence interval. For example, if the sample statistic is 25% with a margin of error or 2.3%, the interval is between 25-2.3 = 22.7% and 25 + 2.3 = 27.3%.
So the correct answer is:
B. There is 85% confidence that the proportion of the adult citizens of the nation that dreaded Valentine's Day is between 0.227 and 0.273
