Multiple Choice

In a regression analysis of a first-order model involving 3 predictor variables and 25 observations, the following estimated regression equation was developed. ​ In a regression analysis of a first-order model involving 3 predictor variables and 25 observations, the following estimated regression equation was developed. ​   = 12 - 18x<sub>1</sub> + 4x<sub>2</sub> + 15x<sub>3</sub> ​ Also, the following standard errors and the sum of squares were obtained. S<sub>b</sub><sub>1 </sub>= 3 S<sub>b</sub><sub>2 </sub>= 6 S<sub>b</sub><sub>3 </sub>= 7 SST = 4900 SSE = 1296 ​ The test statistic for testing the significance of the model is A)  .73. B)  18.93. C)  19.47. D)  1.37. = 12 - 18x1 + 4x2 + 15x3
