It is collectively examined whether with the three variables the regression has a significant effect on the prediction. To that end the null hypothesis is established which states that H₀: β₁ = β₂ = β₃ = 0. The alternative hypothesis, which states the opposite of the null hypothesis, states that

   
   
   1. FALSE: All slopes (βs) are unequal to 0.
   2. TRUE: At least one slope (β) is unequal to 0.
   3. FALSE: All slopes (βs) are different.
   
   
   1. All slopes (βs) are unequal to 0: Incorrect
   2. At least one slope (β) is unequal to 0: Correct
   3. All slopes (β’s) are different…: Incorrect
