A researcher is interested in the effectiveness of a new program at reducing the average systolic blood pressure in children with Autism Spectrum Disorder (ASD)
A researcher is interested in the effectiveness of a new program at reducing the average systolic blood pressure in children with Autism Spectrum Disorder (ASD) with a new anti-hypertensive medication. The researcher wants to test the hypothesis that the mean change in systolic blood pressure between pre- and post-intervention is greater than -40 mmHg. Which of the following represents the correct null and alternative hypotheses for the study?
| a. | Ho: µpre - µpost = 40 Ha: µpre - µpost ≠ 0 | |
| b. | Ho: µpost - µpre = 0, Ha: µpost - µpre > -40 | |
| c. | Ho: µpost - µpre = 0, Ha: µpost - µpre > 40 |
