Follow the excel and few basic questions based on xls. 

a. Develop a scatter chart for these data. What does the scatter chart indicate about the relationship between total points earned and hours spent studying?

b. Develop an estimated regression equation showing how total points earned is related to hours spent studying. What is the estimated regression model?

c. Test whether each of the regression parameters is equal to zero at a 0.01 level of significance. What are the correct interpretations of the estimated regression parameters? Are these interpretations reasonable?

d. How much of the variation in the sample values of total point earned does the model you estimated in part (b) explain?

e. Mark Sweeney spent 95 hours studying. Use the regression model you estimated in part (b) to predict the total points Mark earned.

f. Mark Sweeney wants to receive a letter grade of A for this course, and he needs to earn at least 90 points to do so. Based on the regression equation developed in part (b), how many estimated hours should Mark study to receive a letter grade of A for this course?
