Re: Romney 46% - Obama 31%
Posted by Concourse Express on Thu Apr 26 12:13:55 2012, in response to Re: Romney 46% - Obama 31%, posted by RIPTA42HopeTunnel on Thu Apr 26 10:52:43 2012.155 nationally, margin of error ±8%.
With a margin of error of ±8%, the respective confidence intervals for Romney and Obama are:
Romney: (0.38, 0.54)
Obama: (0.23, 0.39)
So there exists a set of outcomes where Obama beats Romney; that, combined with the remaining 23% of the sample who were presumably undecided, shows there's insufficient evidence at whatever the level of significance was for this poll that Romney beats Obama.
