b) There’s a 78% chance that the ads worked.

c) There’s a 22% chance that the null hypothesis is true.

d) There’s a 22% chance that natural sampling variation could produce poll results like these if the use of the oneclick feature has increased.

e) There’s a 22% chance that natural sampling variation could produce poll results like these if there’s really no change in website use.
