Does cable video-on-demand (VOD) increase ad effectiveness? A study compared general TV and VOD audiences after viewing a brand ad. Whether the viewer indicated that the ad made them want to visit the brand website was collected and organized in the accompanying table. Complete parts (a) through (b) below. Test at the 1% level of significance. Set up null and alternative hypotheses to try to determine whether there is a difference in ad impact between general TV viewing and VOD viewing. Let group 1 be the general TV audience, and let group 2 be the VOD audience. State the null and alternative hypotheses. Choose the correct answer below. A. H0: P1P2 E. H0: P1>P2 H1: P1≤P2 F. H0: P1≥P2 H1: P1

Set up null and alternative hypotheses to try to determine whether there is a difference in ad impact between general TV viewing and VOD viewing.
Let group 1 be the general TV audience, and let group 2 be the VOD audience. State the null and alternative hypotheses. Choose the correct answer below.
A.
H0: P1<P2
H1: P1≥P2
H0: P1=P2
H1: P1≠P2
H0: P1≠P2
H1: P1=P2
H0:
P1≤P2
H1:
P1>P2
H0: P1>P2
H1: P1≤P2
H0: P1≥P2
H1: P1<P2
Calculate the test statistic.
Conduct the hypothesis test defined in (a), using the 0.01 level of significance.
χ2STAT= ___
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
