Do not reject H0; there is not sufficient evidence that the average starting salary of college graduates has declined from 2008 to 2010.

Answer 1

Reject H0; there is evidence that the average starting salary of college graduates has declined from 2008 to 2010.

Explanation:

To be able to reject the null hypothesis, it means the researcher has sufficient statistical evidence to reject the null hypothesis (claiming no difference or association between specified populations).

The null in this case is that the average starting salary of college graduates has not declined from 2008 to 2010.

Thus, in this case study, to conclude that the average salary has gone down from 2008 to 2010, we reject H0 as there is evidence that the average starting salary of college graduates has declined from 2008 to 2010.
