Statistics - Five Step Hypothesis

Five Step Hypothesis

Null should be: There is a difference between male and female salaries at all levels

ALternate should be: There is no difference between male and female salaries at all levels.

The conclusion of the parametric should be "Do Not Reject Ho"

contingency table Observed
Education male female total
High School 28 33 61
2 year college 8 7 15
4 years or higher 17 6 23 #NAME?
total 53 46 99

contingency table Expected
Null should be:  There is a difference between male and female salaries at all levels male female total
