Answer 2

Question 1

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
Part 1: Create a scatter plot with the predicted line of best fit drawn on it. Determine the type of correlation (if any), and predict the model that will be used.
This is a positive correlation. The model best used for this would be a positive linear model.
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.
0.965x+45.547
Y=95.727
Y=81.252
Y=75.462
Y=54.232
Y=70.637
Y=84.147
Y=66.777
Y=55.197
Y=88.972
Y=78.357
Y=63.882
Y=103.447
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.)
