The national average for the percentage of high school graduates taking the SAT is 49%, but the state averages vary from a low of 4% to a high of 92%. A random sample of 300 graduating high school seniors was polled across the Cincinnati Tristate Area, and it was found that 195 had taken the SAT. Estimate the true proportion of high school graduates in this region who take the SAT with 95% confidence. What are the logical steps you are going to follow for answering the main question? A.) Calculate point estimate, Za/2 , margin of error, and then the CI. B.) Calculate Za/2, margin of error, CI, and then point estimate. C.) Calculate Za/2, point estimate, margin of error, and then the CI.
