An initial survey reports 68 percent support for a fee increase. A short follow-up with a random sample of original nonrespondents finds only 32 percent support. Which conclusion is most justified?
A
Exactly 32 percent of the entire population supports the increase.
B
The original survey’s sampling frame must have excluded every opponent.
C
The follow-up proves that the wording of the original question was leading.
D
The original estimate was likely biased upward because opponents were underrepresented among respondents.
E
The two percentages should simply be averaged without considering group sizes or response probabilities.
