Question
Help The number of initial public offerings of stock issued in a 10-year period and the total proceeds of these offerings (in millions) are shown in the table. The equation of the regression line is y 50.095x 17,379 52. Complete parts a and b | 420 | 466 | 678 | 485 | 485 | 387 | 67 | 70 | 192 | 174 17,529 29,653 44,378 30,634 66,330 66,774 20,361 10,040 31,946 27,675 17,529 29,653 44,378 30,634 66,330 66,77420,361 10,040 31,946 27675 (a) Find the coefficient of determination and interpret the result Round to three decimal places as needed.) How can the coefficient of determination be interpreted? O The coefficient of determination is the fraction of the variation in roceeds that is unexplained and is due to other factors or sampling error. The remaining fraction of the variation is explained by the variation in issues The coefficient of variation is unexplained and is due to other factors or to sampling error nation is the fraction of the variation in proceeds that can be explained by the variation in issues. The remaining fraction of the (b) Find the standard error of estimate s, and interpret the result Click to select your answer(s) 1:04)Explanation / Answer
We got regression output from excel :
a) The coefficient of determination is given by
R2 = 0.285
Interpretation of coeficient of determination :
The coefficient of determination is the fraction of the variation in proceeds that can be explained by the variation in issues . The remaining fraction of the variation is unexplained and is due to other factors or to sampling error .
The standard error of estimate :
Se = 17257.15
Interpretation :
The standard error of stimate of the proceeds for a specific number of issues is about Se million dollars.
