4. Ryan surveyed several college students in a particular class and asked them how many hours they studied for their final exam and what score they received. The data is contained in the following table.
Hours spent studying (x): 0, 4, 1, 0.5, 5, 2, 7
Final Exam Score (y): 62, 86, 60, 68, 89, 78, 69
He uses the points (0, 62) and (7, 96) to create the line of best fit. What function represents Ryan's line of best fit, and now many hours would you predict a student would have to study if they want to score an 8080 on the final exam?
A) Ryan's line of best fit is represented by the function y=4.86x+62 and a student would have to study for approximately 3.7 nours to score an 8080 on the final exam.
B) Ryan's line of best fit is represented by the function y=4.86x+62, and a student would have to study for approximately 2.5 hours to score an 8080 on the final exam.
C) Ryan's line of best fit is represented by the function y=7.25x+52.75. and a student would have to study for approximately 3.7 hours to score an 8080 on the final exam.
D) Ryan's line of best fit is represented by the function y=0.21x+62 and a student would have to study for approximately 3.7 hours to score an 8080 on the final exam.
