A December 2017 Gallup Poll reported that 43% of Americans use the internet for an hour or more each day. You suspect that a greater proportion of students at your school use the internet that much. You take a random sample of 60 students and find that 36 of them use the internet for an hour or more each day. Assume your school has more than 600 students. You will test the hypotheses H, : p = 0.43, H,:p>0.43 , where p = the true proportion of students at your school who use the internet for an hour or more each day. Which of the following gives the correct test statistic for this test? 0.43 -0.6 (0.6)(0.4) 60 0.43 -0.6 (0.6)(0.4) 600 0.6-0.43 (0.6)(0.4) 60 0.6- 0.43 (0.43)(0.57) 60 36 - 60 Z= (36)(24) 60
