Johan and Marti were having a discussion about confidence intervals. Marti indicated that as the level of confidence increases the confidence interval gets smaller because the more confident you are the more precise your interval needs to be. Johan on the other hand indicated that as the level of confidence increases the confidence interval gets bigger because the more confident you are the wider the interval needs to be in order to capture the true population proportion within the interval. What do you think? Explain using what you have learned about margins of error.
