In a recent Super Bowl, a TV network predicted that 48 % of the audience would express an interest
in seeing one of its forthcoming television shows. The network ran commercials for these shows
during the Super Bowl. The day after the Super Bowl, and Advertising Group sampled 103 people
who saw the commercials and found that 46 of them said they would watch one of the television
shows.
Suppose you are have the following null and alternative hypotheses for a test you are running:
