Students who complete their exams early certainly can intimidate the other students, but do the early finishers perform significantly differently than the other students?
Please see attached file for problem. Please show work, so that I may understand how to do a similar problem. Thanks!
Step by step method for regression analysis is discussed here. Regression coefficients, coefficient of determination, scatter diagram and significance of regression model are explained in the solution.
