Researchers are wondering whether they can predict college GPA with the number of hours studying per week. To test this, they randomly select 8 college students, record their GPA and the number of hours spent studying per week. GPA 2.5 2.7 3.4 3.7 2.7 1.9 2.0 4.0 ID 1 2 3 27.6 30.2 35.0 31.6 25.6 30.0 40.0 Based on the information in the table above, the researchers compute the regression equation: Y = -0.970+ 0.125 X. Do the researchers have enough evidence to claim that the number of hours studying predicts students' GPA? 4 5 6 Hours studying per week 25.0 7 8 Based on the analysis, what would be the predicted GPA for someone who studies 30 hours per week?
