(Please use mini tab if possible)The variable Hours Studied represents the number of hours a student studied for their final exam and the variable Final Exam Grade represents the final exam score the student received on their final exam (out of 100 points).An introduction, explanation/interpretation of your analysis, and a conclusion.

Hours studied- 1, 0, 7, 9, 9, 5, 4, 2, 11, 7, 13, 3, 3, 1, 9, 7, 5, 0, 2, 8

Final Exam grade 70, 54, 81, 92, 90, 78, 75, 68, 98, 84, 100, 78, 79, 72, 88, 85, 83, 55, 73, 86

7) Generate a scatterplot with a fitted regression line.

8) Interpret the meaning of the slope of the regression line in terms of Hours Studied and Final Exam Grade.

9) What is the y-intercept of the regression line and what does it mean regarding Hours Studied and Final Exam Grade? Is this realistic?

10) Use your regression equation to predict the final exam grade if a student randomly selected studied for thirty hours. Is this realistic?

11) What is the value of the coefficient of determination and what does it mean regarding this data set?

Create a class named Student. Student has fields for an ID number, number of credit hours earned, and number of points earned. (For example, many schools compute grade point averages based on a scale of 4, so a three-credit-hour class in which a student earns an A is worth 12 points.) Include methods to assign values to all fields. Student also has a field for grade point average. Include a method to compute the grade point average field by dividing...
