The table below shows the study time and test scores for a number of students. Study Time(min) 10 15 18 25 35 41 50 Test Score 61 72 74 81 89 90 95 A) Draw a scatterplot that is suitable for predicting test scores based on study time. Please include labels for the x and y axis. B) Determine the shape of the best-fit model for the data (linear, quadratic, exponential, logarithmic, or sinusoidal). Why? C) Find the best-fit regression model for the following data. D) What does the residual plot look like? E) Using the model found in part C, predict the test score of a student who studies for 60 minutes. Please show your work for full credit. F) What does a residual of 2 mean in context of study time and test score?
