Current Attempt in Progress A survey on 1,500 high school seniors who took the SAT and who completed an optional web survey shows that 55% of high school seniors are fairly certain that they will participate in a study abroad program in college. Does this survey provide convincing evidence that the majority (more than 50%) of all high school seniors who take the SAT are fairly certain they will participate in a study abroad program in college? State the null and alternative hypotheses in proper notation. O Ho: 1 = 0.50 vs Ha; 1 = 0.55 O Ho: n = 0.55 vs Ha: # > 0.55 O Ho: n = 0.50 VS Ha: # > 0.50 O Ho: P = 0.50 vs H.: p > 0.50
