A) H₀: β₂ = β₃ = β₅ = 0
B) H₀: β₄ = β₅ = 0
C) H₀: β₃ = β₅ = 0
D) H₀: β₂ = 0

Quizplus · Accepted Answer

The null hypothesis should test the coefficients that correspond to the variables indicating cove and non-cove properties, which in this case are β₃ and β₅. Thus, the correct null hypothesis is H₀: β₃ = β₅ = 0. The other options do not include the relevant coefficients.
