Can you please help me answer the following as I got this incorrect on my assignment: Question: Relate to this specific scenario: What is the null hypothesis? What is the alternate / research hypothesis? Which one do you statistically assess? My answer that was marked incorrect: The null hypothesis states that there is no difference or correlation between a person's heart rate and exam score. The alternative: A person's heart rate and predicted test score are related. An inferential statistical test is performed on the null hypothesis. Professor feedback to change and resubmit: not either of these words is most appropriate - scenario states prediction To measure whether test performance can be predicted based on one’s anxiety, a researcher asked his students to come to the lab 15 minutes before they were to take an exam in his class. The researcher measured the students' heart rates and then matched these scores with their exam performance after they had taken the exam. Use the data below and SPSS to test whether heart rate can predict test performance in the population.
