A random sample of adults was asked whether they prefer reading an e-book over a printed book. The survey resulted in a sample proportion of p' = 0.14, with a sampling standard deviation of ĂŹĆ’p' = 0.02, who preferred reading an e-book. Use the empirical rule to construct a 95% confidence interval for the true proportion of adults who prefer e-books.

A survey of 430 randomly chosen adults found that 21% of the 222 men and 18% of the 208 women had purchased books online. Does the data indicate there is a difference in the proportion of men and women who purchase books online? Which hypotheses could be used to test that there is no difference in the percent of men and women who purchase books online? Ho: p(men) = p(women) HA: p(men) ≠p(women)
