   Question

   A researcher wants to know whether households in the Netherlands (group 1) are more economical about their water consumption than French households (group 2). The variable “water consumption” is measured with the amount of water consumed per day, for which a t-test for two independent groups is used.

   What is the used null hypothesis in this study?

   
   
   1. FALSE: H₀: μ₁ = 0 and μ₂ = 0.
   2. FALSE: H₀: μ₁ ≠ μ₂.
   3. TRUE: H₀: μ₁ - μ₂ = 0.
   4. FALSE: H₀: μ₁ - μ₂ ≠ 0.
