We fail to reject the null hypothesis. There is, at the 0.10 level of significance, sufficient evidence of a linear relationship between starting salary and
GPA.
We reject the null hypothesis. There is, at the 0.10 level of significance, sufficient evidence of a linear relationship between starting salary and GPA.
