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.
