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. Student Heart Rate Exam Score A 76 78 B 81 68 C 60 88 D 65 80 E 80 90 F 66 68 G 82 60 H 71 95 I 66 84 J 75 75 K 80 62 L 76 51 M 77 63 N 79 71 Q: Relate to this specific scenario: What is the null hypothesis? What is the alternate / research hypothesis? Which one do you statistically assess? Q: Present the results using APA format. This includes a full write-up to include a complete statistical notation. The write-up also needs interpretation. If significant, state how. If it is not significant, what does that mean in layman’s terms?
