A polling organization surveys 400 registered voters and finds that 52% support a ballot measure, with a margin of error of ±4.9% at a 95% confidence level. A rival organization surveys 900 voters and finds 49% support, with a margin of error of ±3.3%. Which of the following conclusions is best supported by these two surveys taken together?
-
A
The ballot measure is likely to pass because the first survey shows majority support.
-
B
The true level of support cannot be determined to be above or below 50% with confidence, since the confidence intervals from both surveys overlap and include 50%.
-
C
The second survey is more reliable because it has a smaller margin of error, so 49% should be accepted as the true proportion.
-
D
The surveys contradict each other, so neither can be used to draw any valid inference.
