   Question

   A researcher wants to know whether there is more litter in the Netherlands than in Germany. The variable ‘litter’ is measured by the amount of litter per m2. A t-test is used for this study. What is the null hypothesis of this research?

   
   
   1. FALSE: The average amount of litter in both the Netherlands and Germany is 0.
   2. FALSE: The average amount of litter in the samples of both the Netherlands and Germany is unknown.
   3. FALSE: There is a difference in the average amount of litter between the Netherlands and Germany.
   4. TRUE: There is no difference in the average amount of litter between the Netherlands and Germany.
   
   

   Solution

   There is no difference in the average amount of litter between the Netherlands and Germany.
   H₀       Mean _Netherlands= Mean _Germany
   The alternative hypothesis is that there is a difference in the average amount of litter between the Netherlands and Germany, more in the Netherlands than in Germany in this example.
   H_a    Mean _Netherlands  >   Mean _Germany
