2.  In addition to the survey items, respondents were asked to report their age as follows:

 

My generation is (AGE)

Generation Y (Born 1981-2000)

Below is output from an ANOVA to test if there are differences in stress levels between age groups.

 

What was is the null hypothesis?

 

What is the alternative hypothesis?
