A school principal claims the graduation rate at a school is 96%. Molly, a student at this school, takes a random sample of stud
ents and finds the 95% confidence interval for the true proportion of students graduating from this school is (0.934, 0.983). Is it reasonable to conclude the principal’s claim is incorrect? No, because the interval contains 0.96. No, because the interval contains values greater than 0.96. Yes, because the interval has values less than 0.96. Yes, because a different sample might give different results.
