b. Decide whether using the​ two-proportions z-procedures is appropriate.
 
Check that the assumptions are satisfied. Select all that apply.
 
 
A.
The assumptions are​ satisfied, so using the procedures is appropriate.
 
B.
Since
x2
is less than​ 5, using the procedures is not appropriate.
 
C.
Since
x1
is less than​ 5, using the procedures is not appropriate.
 
D.
Since
n2−x2
is less than​ 5, using the procedures is not appropriate.
 
E.
Since
n1−x1
is less than​ 5, using the procedures is not appropriate.
 
c. If​ appropriate, use the​ two-proportions z-test to conduct the required hypothesis test. What are the hypotheses for this​ test?
 
 
A.Upper H 0 : p 1 greater than p 2 comma Upper H Subscript a Baseline : p 1 equals p 2
H0: p1>p2, Ha: p1=p2
 
B.Upper H 0 : p 1 equals p 2 comma Upper H Subscript a Baseline : p 1 less than p 2
H0: p1=p2, Ha: p1<p2
 
C.Upper H 0 : p 1 equals p 2 comma Upper H Subscript a Baseline : p 1 greater than p 2
H0: p1=p2, Ha: p1>p2
 
D.Upper H 0 : p 1 equals p 2 comma Upper H Subscript a Baseline : p 1 not equals p 2
H0: p1=p2, Ha: p1≠p2
 
E.Upper H 0 : p 1 less than p 2 comma Upper H Subscript a Baseline : p 1 equals p 2
H0: p1<p2, Ha: p1=p2
 
F.Upper H 0 : p 1 not equals p 2 comma Upper H Subscript a Baseline : p 1 equals p 2
H0: p1≠p2, Ha: p1=p2
