Do college students prefer printed textbooks to electronic textbooks? You work for a textbook publisher and want to estimate the population proportion of all college students who prefer printed textbooks to electronic textbooks. So, you will survey 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. (If necessary, consult a list of formulas.) (a)Click on "Take Sample" to see the results from the random sample. Take Sample Number Proportion Prefers printed textbooks to electronic textbooks 51 0.75 Does not prefer printed textbooks to electronic textbooks 17 0.25 Enter the values of the sample size, the point estimate of the population proportion, and the critical value you need for your 95% confidence interval. (Choose the correct critical value from the table of critical values provided.) When you are done, select "Compute".
