An education researcher claims that at most 4% of working college students are employed as teachers or teaching assistants. In a random sample of 600 working college students, 6% are employed as teachers or teaching assistants. At α=0.05, is there enough evidence to reject the researcher's claim? Complete parts (a) through (e) below. (a) Identify the claim and state H0 and Ha. Identify the claim in this scenario. Select the correct choice below and fill in the answer box to complete your choice. (Type an integer or a decimal. Do not round.)
