QUESTION 1The table represents data collected on the time spent studying (in minutes) and the resulting test grade.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. 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. 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.)QUESTION 2Look back at the data from the New York Marathon.Use this original data, but update it with the following information so that it is accurate through 2011.
