What is your conclusion for the overall regression model (also called the omnibus test)?

  • The overall regression model is statistically significant at α=0.02α=0.02.
  • The overall regression model is not statistically significant at α=0.02α=0.02.



Which of the regression coefficients are statistically different from zero?

  • neither regression coefficient is statistically significant
  • the slope for the first variable b1b1 is the only statistically significant coefficient
  • the slope for the second variable b2b2 is the only statistically significant coefficient
  • both regression coefficients are statistically significant
