Determining the Hypotheses The national average SAT score is roughly 1500. We would like to examine if the high school seniors who apply to Duke have higher than average SAT scores. We randomly sample 100 Duke applicants' files and record their SAT scores. Which of the following is the correct set of hypotheses for this research question? H0: μ = 1500; HA: μ > 1500 H0: μ = 1500; HA: μ < 1500 H0: p = 1500; HA: p > 1500 H0: x = 1500; HA: x > 1500 H0: μ = 1500; HA: μ ≠ 1500
