Calculate Regression equation Example 17.2 We take another example of multiple regression analysis. This also relates to sales andadvertising. However, in this example we have taken personal selling (number of selling agents) as oneindependent variable and overall advertising as another independent variable.Table 17.2 Original DataSales TerritorySales (Lakh Rs) (Y) Advertising ('000 Rs) (X}Number of Selling Agents (X,)110040102803010360207120501515060209040127702081306014

A study tests the effect of earning a Master's degree on the salaries of professionals. Suppose that the salaries of the professionals (S,) are not dependent on any other variables. Let D, be a variable which takes the value 0 if an individual has not earned a Master's degree, and a value 1 if they have earned a Master's degree. What would be the regression model that the researcher wants to test? A. S,= Po + B,D,+u, i=1, .. , n. O B. S,= Po + B, + u, i= 1, .. , n. OC. 1=6o +B1,S, + u, i= 1, .. , n.

We wish to predict the salary for baseball players (y) using the variables RBI (x1) and HR (x2), then we use a regression equation of the form ˆy=b0+b1x1+b2x2y^=b0+b1x1+b2x2. HR - Home runs - hits on which the batter successfully touched all four bases, without the contribution of a fielding error. RBI - Run batted in - number of runners who scored due to a batters's action, except when batter grounded into double play or reached on an error Salary is in millions of dollars. The following is a chart of baseball players' salaries and statistics from 2016.
