The table represents data collected on the time spent studying (in minutes) and the resulting test grade.
Time Spent Studying (min) 52 37 31 9 26 40 22 10 45 34 19 60
Grade on Test 95 84 72 58 77 86 72 43 90 81 62 98

Answer 1

Part 2: Find the line of best fit for the data either by hand or using technology. Explain your method. Find the predicted score for each time listed in the table.
Y=45.547+0.965x
Y is the predicted grade, and x is the time spent
Time – predicted score
52 - 95.727
37 – 81.252
31 – 75.462
9 – 54.232
26 – 70.637
40 – 84.147
22 – 66.777
10 – 55.197
45 – 88.972
34 – 78.357
19 – 63.882
60 – 103.447

Answer 2

Part 3: Find the residuals, and decide if your model is a good fit. Explain your method. (If your model is not a good fit, complete Part 2 again with a different set of points or choose a different model.)
