Q4. Professor Video, a college psychology instructor, wants to determine if there is a negative linear correlation between a student’s GPA and the number of hours a student spends playing video games per week. She randomly selected twenty students from all her classes and determined their number of hours playing video games per week and their GPA. The sample results were: GPA: 4.00 2.50 3.95 3.90 3.80 2.90 3.10 3.25 1.35 4.00 Hrs Playing: 0 15 3 5 0 13...
