We all know that studying helps you do better on exams, but is that effect moderated by how much sleep you get the night before the exam takes place? To answer this, researchers conducted an experiment on students in a Biostascs class. The night before taking an exam, 60 students were randomly divided into 3 groups: a \"no sleep" group was kept up all night, a "low sleep" group was only allowed to sleep 4 hours, and a "high sleep" group was allowed to sleep 8 hours. In addition to their exam grades [ranging from 0-100), the researchers also measured how many hours each student studied for the exam. They conrmed all relevant assumptions and ran a multiple linear regression, including interaction, with the following results: Estimate SE t p-value Intercept 57.82 16.72 3.46 0.001 StudyDu ration 4.22 1.60 2.64 0.010 Sleep_Low 12.67 5.87 2.16 0.035 Sleep_High 19.11 6.18 3.09 0.003 StudyDuration*Sleep_Low 0.54 0.33 1.64 0.108 StudyDuration'Sleep_High 1.14 0.43 2.65 0.01 1 Provide the slope estimates for StudyDuration on ExomGrade for students in the "no sleep" and "low sleep" groups.
