Thelma and Louise are each attempting to estimate the proportion of adults who enjoy listening to country music.  They each survey a different random sample of adults, and in each sample, the proportion who say they enjoy listening to country music is 0.29.   Thelma and Louise each use their sample data to construct a confidence interval.  Thelma’s interval is from 0.242 to 0.338 and Louise’s interval is from 0.237 to 0.323.  One of these intervals was computed correctly and the other was not.  Which interval must be the correct one?
