O B. At most
% of college students work year-round.
O C. The percentage of college students who work year-round is not
O D. At least
% of college students work year-round.
Let p be the population proportion of successes, where a success is a college student who works year-round. State H, and Ha. Select the correct
choice below and fill in the answer boxes to complete your choice.
