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 = 47.743x + 17,860.44. Complete parts a and b. Issues, x 420 455 694 483 483 387 71 65 192 165 Proceeds, 17,681 28,269 43,156 30,438 65,385 67,427 20,363 10,378 30,594 27,956 y ..... (a) Find the coefficient of determination and interpret the result. 0.270 (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 proceeds 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 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. (b) Find the standard error of estimate s, and interpret the result. (Round to three decimal places as needed.)
