The advertising manager at the Summit Record Company is interested in buying advertising time on TV. He is thinking about running ads on Channel 32, a local channel. The channel claims that more than 20% of TV viewers are tuned in from midnight to 1AM every night. The record company hires someone to check this and they collect data that says that out of 400 viewers one night, 96 of them were watching Channel 32. In light of this, does Channel 32's claim hold up? Use a .05 level of significance.
