   Which of the following alternatives is the null hypothesis?

   
   
   1. FALSE: Age group and spot preferred are correlated.
   2. TRUE: Age group and spot preferred are independent.
   3. FALSE: The distribution for preferred spot is not the same for all age groups.
   4. FALSE: Frequencies in all categories are the same.
   
   
   1. The null hypothesis always assumes no difference or no correlation.
   2. The null hypothesis in this chi-square distribution is that the variables are independent.
   3. The null hypothesis always assumes no difference or no correlation.
   4. The hypothesis does not relate to the frequencies, as these always depend on the sample size.
