please show all the work. if you use excel please show the screenshots. Thank you ! Question 5 (25pts) Suppose the athletic director at a university would like to develop a regression model to predict the point differential for games played by the men's basketball team. A point differential is the difference between the final points scored by two competing teams. A positive differential is a win, and a negative differential is a loss. For a random sample of games,...
please show work, see data attached Question 5 (25pts) Suppose the athletic director at a university would like to develop a regression model to predict the point differential for games played by the men's basketball team. A point differential is the difference between the final points scored by two competing teams. A positive differential is a win, and a negative differential is a loss. For a random sample of games, the point differential was calculated, along with the number of...

a) Find the multiple regression equation using all three explanatory variables. Assume that X1 is mid-term score, X2 is hours studying per week and x3 is hours watching television per week. Give your answers to 3 decimal places. û = mid-term score + hours studying + hours watching television + b) At a level of significance of 0.05, the result of the F test for this model is that the null hypothesis rejected. c) The explanatory variable that is most...
