   Question

   One researcher claims that girls (group 1) receive less pocket money than boys (group 2). He tests this one-sided hypothesis and uses a significance level (alpha) of 5%.

   In this case, what is the zero hypothesis?

   
   
   1. TRUE: H₀: µ1 - µ2 = 0.
   2. FALSE: H₀: µ1 ≠ µ2.
   3. FALSE: H₀: µ1 + µ2 = 0.
   4. FALSE: H₀: µ1 < µ2.
   5. FALSE: H₀: µ1 = 0 and µ2 = 0.
   6. FALSE: H₀: µ1 < 0 and µ2 = 0.
   
   
   1. True
   2. False
   3. False
   4. False
   5. False
   6. False
