Reason:
The confidence interval for the population proportion p is (0.34, 0.43)
This is equivalent to saying 0.34 < p < 0.43
We're 95% confident p is somewhere between 0.34 and 0.43
Both of these endpoints are smaller than 0.45, meaning that all of the proportions p in the interval are smaller than 0.45
So it's fairly reasonable to assume that less than 45% of the Floridian voters are democrats (since it seems to be between 34% and 43%). Keep in mind that there's always a margin of error with statistics, so we cannot say this with 100% certainty.
