Suppose you are interested in estimating , the percentage of university students who receive some type of financial aid. To this goal, you administer a survey to poll some randomly selected sample of students. You do some work in R, then you obtain an estimate of the fraction of students receiving financial aid from your data. By default, R returns a level confidence interval for your estimand (default is ). Which of the following is true? (Select all that apply) You are 95% sure of your estimate of the exact, correct value of the true effect. If you compute the interval in repeated samples, then -percent of the time, the interval will bracket the true fraction . is the significance level of the test
