Complete a T-test for the following data:
Q: The random error for this test comes from the fact that salary can have a variety of ranges based on type of occupation, personal ability, plus many other items. What we are saying is that primarily people make more money as they get older regardless of other issues. We are using a large sample group for a better analysis.We can expect a positive slope (you make more money as you get older) so we can use a right tailed test which means we can reject a null hypothesis. Speaking of which:
H0: B1 = 0
H1: B1 > 0
The null stating that there would be no change signified by a zero slope. The alternate stating there will be a change for the positive by age.
X11: age - X1: wages
