Use the confidence interval to evaluate this claim and select the true statement.
Answer
A
Yes, it is reasonable to assume this because all reasonable values in the confidence interval are greater than 0.50.
B
We cannot determine this without taking a census of all city-dwellers.
C
No, it is not reasonable to assume this because another 95% confidence interval might not be entirely above 0.50.
D
No, it is not reasonable to assume this because there are only two choices and the proportion of city-dwellers who should prefer either is exactly 0.50, not more than 0.50.
