#1 Related to Regression Analysis Give an example of a regression model in a business setting. Explain in detail. Note: there will not be any points given for an example similar to a problem in this exam . #2. Related to Regression Analysis We have the simple regression model Y = a + b X where a is the value of the intercept, b is the value of the slope, Y is the value of the dependent variable , and X is the value of the independent variable. a) What is the definition of the slope in a regression model? b) If X = 0, what is the predicted value of Y in the simple regression model? c) In a regression model, what statistic can you use to show whether X and Y are weakly or strongly linearly related? Define this statistic. d) If a scatter plot of the data looks like the graph below, what do you think would be the value of the slope in a regression equation? #3. Related to Regression Analysis Explain in detail the difference between simple and multiple regression analysis. Please give an example if it is possible 1
