A recent survey of 128 high school students indicated the following information about release times from school. -35 percent wanted to start school and hour earlier and get out earlier -20 percent liked things how there are currently -39 percent wanted to start school a half an hour later and get out later in the day. -6 percent had no opinion The margin of error for this survey was calculated to be plus or minus 4 percent. The sample size n=128 Find the interval estimates for those that want to get out earlier and those that want to get out later. Explain how it would be possible for the group that wants to get out of school earlier to win after all the votes are counted.
