     A professor wanted to determine if there is a relationship between class attendance (X), and the student final grades (Y). He obtained the summarized data below about 18 students.  summation x = 158, summation x^2 = 9850, summation y = 1425, summation y^2 = 38250, summation xy = 16540, SSSE = 10275  Use the above information to answer questions 1-3 1.  Determine the least square prediction equation.  Based on the regression model, estimate the attendance is 10.  Can you conclude that there is a useful linear relationship between class attendance and the final grade in this class at alpha = 5%?
