Quizplus · Accepted Answer

The null hypothesis (H₀) is that the true proportion of third class mail read by recipients is equal to or greater than 63.4% (P = 0.634). The alternative hypothesis (H₁) is that the true proportion of third class mail read by recipients is less than 63.4% (P < 0.634). This is the best choice because the environmental group is concerned about waste production and wants to test if the Postal Service's claim of 63.4% is accurate. By testing for a proportion less than 63.4%, they can determine if the Postal Service's claim is overstated and if there is potential for reducing waste by not sending unwanted mail.
