Caleb is a campaign manager for a governor. He is looking into whether the governor's job approval rating among registered voters has increased from 54% in order to provide him with additional information to prepare for the upcoming election. Caleb randomly selects 424 registered voters in the state to ask them if they approve of the governor's job and finds that 237 of the voters in the sample responded with "Yes." Are all of the conditions for this hypothesis test met, and if so, what are the null and alternative hypotheses for this hypothesis test?
