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)	1
	Generation X (Born 1965-1980)	2
	Baby Boomers (1946-1964)	3
	Veterans (Born 1922-1945)	4

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?

Below are summary statistics for
