Allan and Beth are each attempting to estimate the proportion of college students who regularly eat breakfast. They each survey a different random sample of college students, and in each sample, the proportion of students who regularly eat breakfast is 0.35. Allan and Beth each use their sample data to construct a confidence interval. Allan's interval is from 0.336 to 0.384, and Beth's interval is from 0.308 to 0.392. One of these intervals is correct, but the other is not. Which interval must be incorrect? O It's impossible to answer this question without knowing the sample sizes. O It's impossible to answer this question without knowing the level of confidence used for each interval. O Allan's interval must be incorrect. O It's impossible to answer this question without knowing the sample sizes or the level of confidence used for each interval. O Beth's interval must be incorrect
