Determine the equation of the regression line for the Absences/Final Grade data given below. Construct a scatter plot of the data and draw the regression line. A grid is provided for the graphs of the scatterplot and regression line.
Number of Absences x 10 12 2 0 8 5
Final Grade y 70 65 96 94 75 82
Use the regression equation to find the best-predicted value for a student's final grade "y" with x = 7 absences. Then find a 95% prediction interval estimate of the final grade "y" for x = 7 absences. The standard error of estimate se = 2.7755. Note: The standard error of estimate se is given, and you do NOT have to calculate it!!! Use the guidelines on page 517 in our textbook. Interpret the results of your prediction interval.
