In a random sample of 100 adults, 27 say they are in favor of outlawing cigarettes. Let p be the proportion of all adults who are in favor of outlawing cigarettes. A researcher wishes to test the following hypotheses: Ho : p = 0.23; Ha :p#0.23. In this scenario, the appropriate test statistic is: p-Po (a) Z = V Po90/n * - Ho (b) Z || 8//n | (c) T = 8/Vn p-Po (d) Z = VPâ/n
