Presidential Poll. A research group suspects that less than 46% of Americans support the Republican presidential candidate. To test this claim, they randomly call Americans until they get 1000 responses. Of the 1000 people who responded, 457 of them say they support the Republican presidential candidate. Test the research group's suspicion at a 5% level of significance.

(a) Select the correct null and alternative hypotheses.

H_o: p = 0.457
H_a: p < 0.457
H_o: p = 0.46
H_a: p ≠ 0.46
H_o: p = 0.46
H_a: p < 0.46
H_o: p = 0.457
H_a: p ≠ 0.457
H_o: p = 0.457
H_a: p > 0.457
H_o: p = 0.46
H_a: p > 0.46
