H0​: P1≠P2
H1​: P1=P2
 
D.
H0​:
P1≤P2
H1​:
P1>P2
 
E.
H0​: P1>P2
H1​: P1≤P2
 
F.
H0​: P1≥P2
H1​: P1<P2
 
Calculate the test statistic.
Conduct the hypothesis test defined in​ (a), using the 0.01 level of significance.

p-value=____
 
State the conclusion
 
__A__ the null hypothesis, since the p-value is less than α. There is __B__ evidence at the 0.01 level of significance to conclude that there is a difference in ad impact between general TV viewing and VOD viewing. 
 
A: do not reject, reject
B: sufficient or insufficient
