An education researcher claims that at most 7% of working college students are employed as teachers or teaching assistants. In a random sample of 500 working college students, 9% are employed as teachers or teaching assistants. At a= 0.01, is there enough evidence to reject the researcher's claim? Complete parts (a) through (e) below. Let p be the population proportion successes, where a success is a working college student who is employed as a teacher or teaching assistant. State Ho and H,. Select the correct choice below and fill in the answer boxes to complete your choice. (Round to two decimal places s needed.) OA. Ho: p< Họ: ps 0.07 OC. Ho: p= H p2 OD.
