NIMBY. In March 2007, the Gallup Poll split a sampleof 1003 randomly selected U.S. adults into two groups atrandom. Half 1n = 5022 of the respondents were asked,“Overall, do you strongly favor, somewhat favor,somewhat oppose, or strongly oppose the useof nuclear energy as one of the ways to provideelectricity for the U.S.?”They found that 53% were either “somewhat” or “strongly”in favor.

Only 40% were somewhat or strongly in favor. This
difference is an example of the NIMBY (Not In My
BackYard) phenomenon and is a serious concern to
policy makers and planners. How large is the difference
between the proportion of American adults who think
nuclear energy is a good idea and the proportion who
would be willing to have a nuclear plant in their
area? Construct and interpret an appropriate confidence
interval.
