HELP PLEASE? I can not understand this, and I would love the help if possible. 100pts given as well
Thank-you!
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.

I'm not quite sure about the first part (sorry), but from what I can tell, the interval estimates are like the margin of error and the percentages combined. So for example, the 35% that want to start school early have an interval estimate of 31%-39%, the 20 percent that like things as they are have an interval estimate of 16%-24% and so on.

For the second part, since there is a +- 4% margin of error, it is possible that the majority (39% that want to start later) can go down by 4% and the 35% that wanted to start earlier can go up by 4%. Therefore, taking into consideration margin or error, the people that want to get out of school earlier could be the majority and win.
