Food court survey. The food court closest to your dormitory has been redesigned. A survey is planned to determine whether or not students think that the new design is an improvement. Sampled students will respond "Yes" if they think it is an improvement and "No" otherwise.
The redesign will be considered a success if at least half the students view the redesign favorably. State the null and alternative hypotheses you would use to examine whether the redesign is a success.
