Question
A recent study claimed that 66% of the population of all college students prefer printed textbooks to electronic textbooks. You want to test this daim by
surveying a random sample of 68 college students.
Follow the steps below to construct a 95% confidence interval for the population proportion of all college students who prefer printed textbooks to electronic
textbooks. Then state whether the confidence interval you construct contradicts the study's claim. (If necessary, consult a list of formulas.)
(a) Click on "Take Sample" to see the results from the random sample.

(c)
Does the 95% confidence interval you constructed contradict the claim from the study?
Choose the best answer from the choices below.
O No, the confidence interval does not oontradict the claim. The proportion 0.66 from the study is inside the 95%
confidence interval. .
O No, the confidence interval does not contradict the claim. The proportion 0.66 from the study is outside the 95%
confidence interval.
O Yes, the confidence interval contradicts the claim. The proportion 0.66 from the study
