A. Directions: Carefully read and analyze the following situations. Identify the information being asked. Then, determine the critical value and shade the area of the rejection region under the normal curve. 1. Suppose that in the past, 40% of all adults favored capital punishment. Do we have reason to believe that this proportion has increased if in a random How to Create the Rejection Region 14 sample of 150 adults, 80 favored capital punishment? Use a 0.05 level of significance. Ha: O = Critical Value: 2. Professors from a professional organization for private colleges and universities reported that more than 16% of professors attended a national convention in the past year. To test this claim, a researcher surveyed 200 professors and found that 50 attended a national convention in the past year. At o = 0.10, test if the figure in the claim is correct. Ha: O = Critical Value: -3 -2 -1 2 11
