Null Hypothesis: Mean Student Debt in 2011 is equal to Mean Student Debt in 2007 | |
Alternative Hypothesis: Mean Student Debt in 2011 is not equal to Mean Student Debt in 2007 |
d ) the t Test Statistics is 12.32073615
the p-value is 1.25493E-21
e ) since p value is less than 0.05 so we conclude that Mean Student Debt in 2011 is not equal to Mean Student Debt in 2007
