In 1996, 57% of high school teachers felt it was a serious problem that high school students were not being attentive enough in the classroom. A recent survey found that 110 of 200 high school teachers felt it was a serious problem that high school students were not being attentive enough in the classroom. Do high school teachers feel differently today than they did in 1996? (a) What does it mean to make a Type II error for this test? (b) If the researcher decides to test this hypothesis at the α = 0.10 level of significance, compute the probability of making a Type II error, B, if the true population proportion is 0.55. What is the power of the test? (c) Redo part (b) if the true population proportion is 0.52. COLL (a) What does it mean to make a Type II error for this test? Choose the correct answer below. OA. H is rejected and the true proportion of high school teachers who believe that students are not attentive in the classroom is not equal to 0.57. OB. H is not rejected and the true proportion of high school teachers who believe that students are not attentive in the classroom is equal to 0.57. OC. Ho is not rejected and the true proportion of high school teachers who believe that students are not attentive in the classroom is not equal to 0.57.
