Answer 1

Null hypothesis: party affiliation and vote toward the latest budget package are independent

Applying chi square test:

Expected	Ei=row total*column total/grand total	Favour	Oppose	Total
	Democrats	28.21	38.79	67
	Republicans	11.79	16.21	28
	total	40	55	95
chi square    χ2	=(Oi-Ei)2/Ei	Favour	Oppose	Total
	Democrats	1.367	0.994	2.362
	Republicans	3.272	2.379	5.651
	total	4.639	3.374	8.0126

X² obsereved =8.01

X²_critical =3.841

degree of freedom(df) =(rows-1)*(columns-1)=

1

reject Ho

APA-style results : p value <0.05 , conclude party affiliation and vote toward the latest budget package are related
