A school principal claims the graduation rate at a school is 96%. Molly, a student at this school, takes a random sample of students 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?
Answer
A
No, because the interval contains 0.96.
B
No, because the interval contains values greater than 0.96.
C
Yes, because the interval has values less than 0.96.
D
Yes, because a different sample might give different results.
