A recent study claimed that 54% of the population of all college students prefer printed textbooks to electronic textbooks. You want to test this claim by surveying a random sample of 40 college students. Follow the steps below to construct a 90% 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 randam sample. Take Sample Sample size: Point estimate: 0 Critical value: 0 Compute Explanation Prefers printed textbooks to electronic textbooks Does not prefer printed textbooks to electronic Check textbooks Enter the values of the sample size, the point estimate of the population proportion, and the critical value you need for your 90% confidence interval. (Choose the correct critical value from the table of critical values provided.) When you are done, select "Compute".
